Fecal pumps with a grinder: review of models and prices. How to choose a fecal pump with a grinder for cesspools Pump for fecal matter

A submersible fecal pump with a grinder can come to the rescue. You can also purchase a semi-submersible or surface model, depending on specific conditions. Despite the differences in technical characteristics oh and different ways installation of these products, they all have a common fundamental difference from machines for other purposes - the ability to process large, but soft, long-fiber inclusions.

It seems that the name determines for what purposes a fecal pump with a grinder is used - for septic tanks, etc. In fact, the scope of application of such units is much wider. Special devices capable of grinding not only feces, but also other organic inclusions– fallen leaves, algae, food waste, etc. This ensures the passage of contaminated wastewater through the pump, reducing the load on the motor and the likelihood of it jamming. This makes household sewage pumps with a grinder suitable for transporting stormwater, rainwater with leaves, kitchen sink waste and dishwasher.

• Models with shredders are suitable for sewer systems where because of large quantity users cannot control the absence of foreign objects in drains - in campsites, in enterprises.
• Their use in catering units is effective, where vegetable peelings and food residues from washing dishes end up in the drain.
• Using units of this type, you can pump water from natural reservoirs and flooded pits for drainage, as well as supply water containing silt from a lake or pond ( organic fertilizer) for watering.

Sewage pumps are also necessary in cases where the sewer system is made of pipes with a small cross-section (up to 50 mm).

Principle of operation

Grinding of soft (in most cases organic) inclusions in units of this type can be done in various ways.

• The impeller is of a special shape - a screw cone with blades sharpened on the outside.
• A scissor effect created by placing sharp-edged blades close to the lower inner surface of the cylinder.
• Separately, but coaxially with the impeller, knives are installed in front of the chamber entrance.
• The blade unit is installed separately and operates using a gear transmission.

Otherwise, the operating principle and design of fecal pumps are practically no different from similar parameters of drainage models. Pumping units with grinders also consist of a housing and an electric motor (for household models - designed for 220 volts, and for industrial ones - 380 volts).

Another distinctive feature of fecal models is the use of durable and chemical-resistant materials for the manufacture of the body and main components of the units. This allows you to use a fecal pump with a cutting mechanism without any risk of getting abrasive damage when sand or other small solid impurities get into the drains, as well as when there are aggressive substances in the water (for example, cleaning agents, detergents, disinfectants).

Materials for the manufacture of the case can be:

• stainless steel,
• cast iron,
• plastic (budget models not designed for very intensive use).

The shaft with knives and the impeller can be made of stainless steel or steel with a protective coating (against corrosion and the abrasive effects of impurities).

Types of models

All pumping units can be divided into three types according to location and method of installation.

• Submersible a fecal pump with a grinder for pumping out cesspools or other reservoirs operates in the water column. Its advantage is a large lifting capability, crushing inclusions with a diameter of up to 50 mm. The disadvantage of this option is the complexity of inspection, maintenance and repair of equipment.

  

• Superficial the units are located on land, wastewater enters the chamber through a special pipe or hose with a large diameter.
  Such surface fecal pumps are used when the size of inclusions is no more than 5 mm, since they do not have a grinder

  If sewer riser, the septic tank or cesspool is located above the level of the drain point (for example, when the toilet or washing room is located in the basement), a special surface unit is installed next to the drain point (toilet, kitchen sink etc.).

  

• Semi-submersible pumps are installed in most cases in waterproofed receiving wells and do not have grinders. The particle diameter should be no more than 15 mm.

  In a semi-submersible fecal pump, the suction part is immersed in liquid, and the motor is on the surface, which ensures its air cooling

You can classify technology by area of ​​application:

• Industrial fecal pumps with a grinder, which include units for large facilities (enterprises, repair shops, office buildings and institutions), as well as models that transport liquid from the collector of a residential building to the central pipeline of the system, and are used for emptying septic tanks or cesspools (although low-power units of this type can be classified as household).
• Go to category household appliances include pumps for toilets and kitchens installed in apartments and private houses.

An important parameter for evaluating and comparing models when choosing is the ability of pumping units to withstand high temperature liquids.

• A fecal pump with a grinder, used only in the toilet, is usually chosen to work with liquids at low temperatures.
• Models for the kitchen or general collector, where the washing machine and dishwasher drains are discharged, can withstand temperatures up to 80-90° C.

Pump installation

The method of installing the pump depends on its type, and that, to a certain extent, on the operating mode.

For permanent work

For constant pumping of wastewater, it is advisable to choose a submersible or semi-submersible model of a fecal pump. Speaking of semi-submersible pumps, they installed permanently and dismantled only during repairs. The best place for the installation of units of this type - a specially constructed receiving well. Its overall dimensions must be no less than 500x500x500 mm. The receiving well is a kind of storage tank into which all the pipes of the system are inserted (for example, a branch from a house, a bathhouse, an outdoor shower, etc.).

An important nuance of installing units of this type is the need to fine-tune the automation. The pump shutdown threshold should ensure that the well is constantly maintained in a nearly empty state, while preventing air entrapment.

For periodic pumping

Periodically submersible fecal pump with grinder for summer cottage used when emptying the contents of septic tanks or cesspools. In this case, it is not advisable to install a stationary semi-submersible or surface unit. When using portable submersible models, it is important to ensure smooth and accurate installation of the unit into place, for which a cable and special guides are often used. Moving along them, the pump takes the correct position, and after emptying the tank, it is removed in the same way.

To extend the service life of equipment, submersible fecal pumps with a grinder for giving before storage during breaks in operation, they must be cleaned and dried, after which they are sent to a dry, heated room (utility room, pantry, garage, etc.).

Submersible sewage pumps can also be installed permanently

Units for toilets in houses and apartments

Household models for toilets are designed for a wide range of consumers, so their design is as unified as possible and does not require complex work during installation, and there is no need to configure the equipment.

All structural elements are placed in one case made of durable plastic, so the user does not need to perform assembly. On the same body there are connecting flanges with sealing tabs (it is used to directly connect the pump to the toilet). The connection in the sewer pipelines is carried out using special pipes. Their number may vary; the presence of more than one pipe makes it possible to connect additional drain points to the pump.

The pumping unit is turned on automatically - the engine turns on immediately when liquid enters the system and turns off when the container is emptied.

We talked in more detail about the toilet and its use in a separate article.

Popular sewerage units are from the Danish manufacturer of the same name. We have an overview of various models on our website.

You can get advice on choosing a hydraulic accumulator.

Popular models and brands

Grundfos (SEG series)

Grundfos submersible sewage pumps with a grinder are made of durable and chemical- and temperature-resistant cast iron, and the design allows the models to be installed permanently or transported to other sites. This expands the scope of application of the machines and allows them to be used for autonomous sewer systems, storm drains, drainage of tanks, and supply of water for irrigation from natural reservoirs.

The advantages of the brand's products are:

• increased strength of the one-piece body,
• excellent performance characteristics,
• two protective relays that eliminate the possibility of engine overheating.

The brand's product range includes not only submersible, but also surface fecal pumps with a grinder (Sololift series) for toilet waste.

Gilex (Fekalnik series)

Models from this manufacturer are economical, but their low cost is combined with impressive technical capabilities, which makes Gilex pumps popular among household models. Head – from 6 to 11 m, maximum size individual elements impurities – 35 mm, productivity – 150-220 l/min.

Important: Gilex fecal pumps do not have a grinder, take this into account when choosing.

Sprut (model V1300D)

A model of this brand is suitable for those who are looking for a household fecal pump with a grinder, the price of which will be justified by its high performance characteristics. The unit pumps wastewater with temperatures up to +40° C with mechanical impurities up to 5 kg/m3, the maximum size of inclusions is no more than 35 mm.

Herz (WRS series)

Herz fecal pumps compare favorably with their analogues by the presence of protection against possible negative factors(liquid getting into the motor, mechanical damage, overheating, etc.). At the same time, the cost of models when compared with domestic analogues with similar characteristics is only slightly higher.

Fecal pump Herz submersible type

What to look for when purchasing

• Pump power directly affects its capabilities - productivity, pressure, ability to pump water with a large amount of impurities. But the greater the power, the greater the energy consumption of the unit.
• Housing and main components(knives, impeller, shaft) must be made of durable materials (wear-resistant plastic, cast iron, steel).
• Availability protective devices will ensure trouble-free and safe work pumps Protection against overheating can be neglected when operating submersible models - they are cooled naturally by the liquid surrounding them. The units should also be equipped with float switches that control the liquid level and check valves that prevent water flow in the opposite direction.
• The most expensive model does not always have the best characteristics.

Creating comfortable living conditions in a private home is by no means limited to equipping heating, ventilation and air conditioning systems, ensuring an uninterrupted supply of water and electricity, performing high-quality finishing and saturating the premises with comfortable furniture and modern household appliances. You definitely have to think about the “dirty” side of the issue, invisible in Everyday life, but this does not lose its extreme importance. It's about about the problem of collecting and recycling various waste that inevitably accumulates in the process of family life.

One solution is to order a sewage disposal truck to pump out accumulated sewage as the cesspool fills. But in some cases it is quite possible to do it on your own by finding the possibility of waste disposal. But in this case, special equipment will be required, in particular, a fecal pump with a grinder for cesspools. How to choose such a device and what functions it can perform is described in this publication.

General structure of a fecal pump with a grinder

First, let's define the types of fecal pumps, which depend on the location of their installation.

• Surface fecal pumps are self-priming devices capable of lifting a viscous liquid with a significant amount of contaminants from a certain depth through a hose lowered into the waste pit. The sewage disposal machines familiar to most private home owners are equipped with just such a surface self-priming pump.

There are practically no advantages to such a scheme in terms of domestic use. Such pumps are usually very large and heavy, otherwise they will not be able to cope with the suction of viscous liquid from depth. Such bulkiness entails the need for a permanent installation, which, in turn, will require the creation of certain conditions - protection from precipitation and negative air temperatures. Most often, surface pumps are used on treatment plants, in enterprises or agricultural complexes. Purchasing such a device for a private home is an extra hassle, although it will certainly cope with the task of cleaning an ordinary cesspool.

In addition, the operation of the electric drive is always accompanied by noise, which is also amplified by the cooling of the pump - an air circuit is used here, that is, a fan placed on the motor axis, covered with a casing.

• Semi-submersible sewage pumps are almost always permanently installed equipment that requires special installation. The idea is that the electric drive (motor) is located on top, in the air, and the working chamber of the pump is immersed in the waste storage tank. They are connected by a long shaft to transmit torque.

Such pumps have proven themselves well at large facilities, for example, at livestock farms, where regular, almost daily pumping of accumulated waste is required. They also find application in a branched sewage system connected to one volumetric storage tank, which also has to be emptied quite often.

But in conditions household the use of such equipment, which is bulky, difficult to install and requires space, is completely unreasonable.

• The best choice for household use- This is a submersible sewage pump. They are small in size, easy to use periodically or continuously, unpretentious, and operate without noise. They don't need air cooling, since during operation they are in a liquid medium that removes heat well from the electric drive.

Despite the very wide variety of models on sale and the significant range in prices, almost all submersible fecal pumps are configured approximately the same.

All such pumps are a vertically located cylinder. The upper part is the electric drive unit, protected by a housing (item 1), metal, less often – plastic. The power cable (item 2) enters the housing from above, ensuring complete sealing of the entry point. To carry the pump and hang it in a cesspool on a cable, a metal handle (item 3) is rigidly fixed to the body. Special eyes may also be provided to secure the suspension.

Inside the housing there is an electric drive - a stator (pos. 4) and a rotor (pos. 5) which is mounted on vertical shaft(pos. 6) to transmit rotation to the pump part. The shaft rests on groups of bearings (item 7).

Between the electric drive and the working chamber of the pump there is an oil chamber (item 8) - a sealed cavity filled with special technical oil. It performs three functions at once - it ensures a tight fit of the sealing collars to the rotating shaft, ensures constant lubrication of the bearings and serves to remove heat, that is, cool the friction units.

Below is the pump itself - the pumping part. This is a body (item 9) of a certain configuration - a “snail”, in which the working chamber is located. The bottom of the chamber is usually closed with a lid (pos. 10), providing access to the pumped liquid in the center. Often special shape This lid also plays a certain role in grinding waste.

Inside the chamber there is an impeller (item 11) with an impeller. The rotation of the wheel creates a powerful centrifugal acceleration of the liquid, a significant increase in pressure at the periphery of the chamber with a vacuum in the center, which leads to the formation of a flow with high pressure, which is discharged through a special pipe (item 12). The pipe can be stationary, directed upward or perpendicular to the axis of the pump, or it can have a flange connection, and then the direction of the output flow can be changed if desired - upward or to the side. The coupler may have a groove for attaching a hose with a clamp, or a locking part - for special hoses, like firefighters, which, by the way, can also be included in the pump kit - as shown in the illustration.

Fecal pump

Attached to the bottom of the pump is either a support platform with holes for the passage of liquid to the working chamber (item 13), or special legs for reliable installation pump onto a solid base.

As already mentioned, quality fecal submersible pumps are exposed by a cutting mechanism. Does not discharge into wastewater high concentration fibrous waste, paper, fabric, plastic bags, kitchen scraps, etc. In order not to impede the operation of the pump impeller and to prevent the creation of plugs in the hose when pumping liquid, the cutting mechanism will crush these inclusions to sizes that will no longer pose serious interference.

Cutting mechanisms may vary slightly.

• One of the varieties is where a sharpened impeller with knife blades is placed on the shaft in front of the chamber entrance.
• Another type is an impeller blade, the blades of which are tightly ground to the outer plane of the lower cover of the pump’s working chamber.

Essentially, exactly the same principle as in a regular home meat grinder

• The next variety - the knife has a cylindrical shape and is equipped with two cutting edges, and two protrusions are made at the entrance hole into the chamber. When rotating, the cylinder edges and protrusions work like scissors.

• The knife can stand motionless, and the working pair to it, to create the effect of scissors, is created by the edges of the impeller blades.

• Finally, the impeller itself can have a very intricate shape with blades turning into sharply sharpened knives.

It is difficult to say which type is better. When choosing a pump, it would probably be useful to clarify whether it is possible to purchase spare parts for repairing the chopper, and how much they will cost.

Many pumps are immediately equipped with a water level switch with a built-in switch. This allows them to be included in an automated system for pumping out storage tanks. The control unit will turn off the pump when the container is drained to a specified level, and turn it on when the water rises again to a certain level. The presence of a float switch does not in any way prevent the pump from being used in normal, “manual” mode, however, the cost of such devices will be slightly higher.

Of course, different models from leading pump manufacturers may have their own design features, but the design principle outlined above will still remain the same.

What is the functionality of a fecal submersible pump?

The direct purpose of the fecal pump is clear, but it is not limited to this. Its unpretentiousness and high performance open up many other possibilities for use in the most different cases that owners of their own homes have to face.

• If the site is located in a lowland or on marshy soils, then the accumulation of moisture in the basement or basement is often a common occurrence. If you equip them with pits for collecting water, then as they fill, you can pump them out using the same submersible fecal pump. Often the pump is installed permanently in such pits and operates automatically using a float switch.

• If the farm has a submersible sewage pump, then it will always help cope with the consequences of the elements - basements or living quarters, wells, low-lying folds of the site, etc., flooded due to floods, heavy rains, sudden melting of snow or man-made accidents. The presence of a shredder allows you to not worry that dirt or debris that gets into the pump will hinder its operation.

• If the site has a storm and (or) drainage system, then the pump can serve a good purpose here too. With its help, it is possible to prevent wells or collectors from overflowing, for example, during periods of prolonged rain, when the drainage capacity of the wells is simply not enough. It may also be useful for emptying the last chamber of the septic tank - with its help, water is pumped out to filtration fields or even for some useful purpose.

Special bioactivators will help in purifying water in septic tanks and cesspools.

It is in vain that many owners of private houses ignore the use of special biological additives for autonomous sewers. are able to quickly process organic waste into water and harmless mineral sediment, improve the drainage capabilities of storage wells, eliminate bad smell. More details about this can be found in a special publication on our portal.

• Artificial reservoirs created on the site require periodic cleaning and replacement of water. And in this case, a submersible fecal pump may well come to the rescue, which is not afraid of mud deposits at the bottom.

• Finally, in the case where there is a natural body of water - a lake or river - in the immediate vicinity of the site, a pump can also be used for irrigation purposes. Of course, with its very high productivity, there is no point in supplying water directly to irrigation installations, but filling watering containers will not take much time.

In a word, this useful device There will definitely be a use, not even considering its main purpose.

How to choose a fecal submersible pump?

Basic criteria for evaluating a submersible sewage pump

If you decide to purchase a fecal submersible pump for a cesspool, your choice should be guided by a number of certain criteria.

• Pump supply voltage and power consumption. Almost all household-grade submersible fecal pumps are designed to operate from a conventional 220 V 50 Hz network. Power indicators predetermine the rest performance characteristics equipment - its performance, the pressure created, the potential for pumping liquids of high viscosity or with a large amount of contaminants.

For country conditions, a pump with a power of up to 500 W is usually sufficient. But if you plan to regularly maintain an autonomous sewer system in a permanent residence, then it is better to choose a device with a power of about 1 ÷ 1.5 kW.

As power increases, energy consumption also increases, of course. But if the pump has good performance, then long work and it’s not supposed to - usually, even for pumping significant volumes of several cubic meters of water, 5 ÷ 10 minutes are enough, and in such a short period of time it will not “wind up” the electric meter to any degree.

• The performance of a submersible pump is its ability to pump a certain volume within a unit of time. Typically for drainage and sewage pumps this figure is expressed in liters per minute. Even the most “weak” pumps, as a rule, cope with a volume of about 150 l/min. The performance of pumps with a power of 1.5 kW or more can reach 500 ÷ 650 l/min! Half a ton per minute – even a large container won’t take much time!
• Created pressure. This is a measure of the fluid pressure created by the pump at the outlet. Typically, for pumping equipment of this class, this value is expressed in meters of water column. This pressure should be enough to lift liquid waste from depth and deliver it along a horizontal section of the pipe (hose) to the disposal site. We must not forget about the horizontal section, especially since we often have to work with viscous waste, and the hydraulic resistance of the pipe can be quite large. For an approximate calculation, you can focus on the following ratio - 1 meter of created pressure will ensure the movement of liquid along a 4-meter horizontal section.

Typically, household-grade submersible fecal pumps are capable of creating a pressure of 10÷15, sometimes more, meters.

• Case material. Preference should still be given to metal models - they are more reliable. But it must be either cast iron or high-quality stainless steel. Wastewater is a very aggressive environment from a chemical point of view, and ordinary steel will not last long in such conditions.

Pumps in different housings - cast iron, stainless steel and plastic

Cast iron, of course, is cheaper, but its pumps are quite massive, and this will need to be taken into account when choosing a suspension - rope, cable or chain. In addition, cast iron should be handled with a certain degree of caution - the alloy is brittle and can crack under an accentuated impact.

Stainless steel pumps are lighter and look prettier (if that matters in this case...). But such improvements certainly affect the cost of the model.

Plastic pumps cause a lot of controversy, and have not yet won full trust from users. It is clear that modern polymers often even surpass metals in their strength properties, but certain concerns still remain.

• If you plan to automate the pumping process, or to insure yourself in case of your own carelessness, it is better to choose a pump immediately equipped with a float water level sensor with a switch.

Automation connected to the float switch will prevent the pump from running dry after the well or pit is emptied

If you plan to use the pump only in manual mode, then you can save money on this option.

• The pump cannot be lowered to any depth relative to the water surface - this parameter is also specified in the technical characteristics of the product.
• For any pumps intended for pumping dirty water, and for fecal ones in particular, the permissible size of solid inclusions is important. It is usually indicated in millimeters, for example, up to 30 mm - this is considered a good indicator.
• If hot wastewater is to be pumped, the pump must be designed for such operating conditions. Typically, most fecal submersible pumps are designed for cold water– with temperatures up to 35 °C.
• The pump is cooled externally by the liquid in which it is immersed. But as it is pumped out, the power unit may protrude above the water and begin to heat up. Therefore, it is never superfluous to have built-in pump protection against overheating - when the stator windings reach a certain critical temperature electrical circuit will be interrupted.

If there are frequent interruptions in the stable power supply in your area of ​​residence, then the model should have protection against power surges or an extended range of permissible

• The reputation of the equipment manufacturer is important. Of course, it is best to choose models famous brands, foreign and domestic, be sure to clarify how service is organized in the region and how actions will be taken in the event of a complaint about the purchased pump - immediate replacement, refund, sending to the factory for repair, etc.

Unconditional authority is enjoyed by fecal pumps of the brands “Wilo”, “Grundfos”, “Unipump”, “Dzhileks”, “Pedrollo”, “Herz”, “Vikhr”, “Metabo”, “Calpeda”, “ESPA”, “Quattro Elementi” , “Sturm”, “Sprut” and others. But this must be a truly original product, and not a cheap knockoff. Therefore, it is necessary to purchase such equipment exclusively in specialized stores, after carefully reading the accompanying documentation.

A little from personal experience

First, briefly about the background of the issue.

The scene is the city of Bendery, Moldova, Transnistria. The distance from the house to a fairly large river by European standards, the Dniester, is about 500 meters, but the height difference is quite significant, about 6 meters.

We bought the house 14 years ago - in September 2002. Before that, no one lived in it for a couple of years. Among the “conveniences” there was only a tap in the house - there was no toilet, no bath, no shower. The drainage pit is located in the yard, 3.5 meters deep, concrete walls and free drainage from below. The top is closed with a cast iron hatch. By the time of purchase, it was, of course, practically empty.

In the first month of residence, all communal amenities were created, including a bath, toilet, washbasin, automatic washing machine- they were all tied to this particular hole. The only exception was the kitchen - due to the peculiarities of the location of the premises of the house. The drain from the kitchen was led into another hole, which serves as a storm well and is located near the gate to the courtyard.

Why is this being told? The fact is that over 12 years, the intensive use of water by a family of 4 people has never led to an overflow of the sewage pit. Moreover, someone took a bath - almost every day. But two years ago, while carrying out small-scale work in the bathroom, I decided at the same time to call a sewage disposal machine and clean cesspool. There was no good adviser nearby at that time - DO NOT TOUCH THE PIT until it copes with its drainage functions. And I wasn’t smart enough to read forums on the Internet - the ladies were given a lot of recommendations of the same kind in this regard.

In a word, after the pit was pumped out to the bottom, serious problems began. Just a couple of months later, water began to seep up through the hatch. Call the car again - and history repeats itself with enviable regularity. Apparently, the hydrological balance of the well and the surrounding soil was disrupted, and drainage qualities dropped several times.

It’s also a shame that the arriving car literally pumped out only water, since there was a minimum of solid waste. I have been using bioadditives for a long time, and the bacteria work well, so that practically no sludge accumulates.

Paying a lot of money for pumping water is, of course, unreasonable. Each call costs 200 of our rubles (the approximate ratio to the Russian ruble is 1:5.5, that is, one pumpout costs about 1,100 rubles). And after a year and a half of torment, it was decided to distill the water from the sewage pit into the storm pit, into which, as already mentioned, the kitchen sewer was also drained. From there, the water goes into the drainage “with a whistle”, and an approximately stable level is always maintained in the hole.

Laying pipes for overflowing water by gravity was considered unprofitable, since the entire yard is paved concrete slabs(still from the old owners). And so a fecal submersible pump was purchased.

The model cannot be called a brand, but these are the features of our unrecognized region - high-quality equipment It's very difficult to get here with a factory warranty. The packaging indicated that it was made in Russia, Chelyabinsk, but no accompanying documents were included, although the pump was purchased at the largest specialized plumbing store in the city.

However, the price of the issue was very satisfactory - exactly 1000 of our rubles (in Russian rubles, therefore - 5500 rubles).

And with the help of this pump, water has already been pumped from one pit to another four times - that is, 800 rubles for calling a sewer truck have already been “recovered.”

The last time this was done was this morning, June 4th. There were heavy rains for more than a week, and the cesspool “made itself felt.”

The pumping process has already been worked out and can be completed by one person in literally 15–20 minutes.

Illustration	Brief description of the operation performed
	Here it is - the cast-iron hatch of the cesspool. Located in the center of a paved courtyard.
	The yard has a fairly significant slope towards the gate, and in front of the gate there is a storm drain covered with a grate. It leads to the second pit, where we will pump water from the first. The straight line distance between the pits is about 12 meters.
	The slight “debacle” was caused by the fact that work had begun on installing a new plastic hatch on the storm pit - there was a wooden one there, already pretty rotten. Work was temporarily suspended due to prolonged rains. The hatch frame has already been installed, but is not yet fully embedded in the mortar.
	This is the hatch itself, awaiting final installation.
	From the very beginning it was decided not to use a long flexible sleeve, in order to avoid twisting, fraying, etc. A set of three-meter sewer pipes 50 mm - and it turned out to be more profitable in terms of money. The cat appears in the frame for the second time: this is not because I like to “post cats” - this weasel just loves to “help”, no matter what I do.
	For direct connection to the pump, a 50 mm piece of flexible hose was used, the length being the depth of lowering the pump into the pit. By the way, the standard clamp with a bolt that came with the pump turned out to be of little use - it was replaced with a worm clamp. On the other side, the hose ends with a 90° bend - this time for connection to the pipe.
	During the second pumping, a small emergency occurred - a strong pressure at the point where the flow direction changed tore off the outlet from the socket of a straight section of the pipe. At that time, it was still possible to avoid an “odorous shower,” but then measures were taken - the connection is fixed with self-tapping screws: they do not take long to remove or screw into the drilled holes.
	Assembling a straight section is a matter of one minute...
	A flexible sleeve is also used on the opposite side. This is due to the fact that it is necessary to insert the pipe into the storm drain channel. This measure is temporary, and after the hatch is ready, a straight structure ending in a rectangular outlet will be used.
	The storm grate is raised and the pipe is inserted into a channel that goes into a storage and drainage well (pit).
	To suspend the pump in a sump pit, the most inexpensive option– nylon rope 12 mm – this will be quite enough. For ease of lowering and lifting, knots are tied on it. The loop will be suspended from a piece of steel angle placed on top of the open hatch.
	Everything is prepared - you can open the hatch. Yesterday the water came out. Today the level has dropped somewhat, but is still critical. Any use of even 50 liters of water will result in overflow.
	Carefully releasing the rope (under no circumstances - not by the power cable!), lower the pump into the sump pit.
	Fully ready to start pumping. The procedure was initially planned to be carried out in visual control mode, so we did not bother with the float switch.
	We plug in the power cable and watch the process.
	The hum of the pump is practically inaudible, only a slight vibration. The water level is rapidly falling before our eyes.
	At the other end of the “main”, the flexible hose was inflated from the pressure of the pumped water.
	The pumping lasted 8 minutes. About three cubic meters of water (the hole expands much from the neck down) were transferred to the drainage well. Now for 2–3 months there will be no problems.
	It is advisable to flush the pump immediately. Place it in a container with water and turn it on for 10÷15 seconds. At the same time, we supply water into the container through a garden hose. The inside of the working chamber of the pump and at the same time all the hoses and pipes are washed.
	The cesspool hatch is in place. We disassemble the pipe connections and put them in the garage for storage until next time.
	We rinse the pump and the hose attached to it from above thoroughly with water pressure, and can also be sent for storage.

So, the whole procedure took about 15–20 minutes, without the involvement of assistants, and this also takes into account pauses for photography. By the way, driving a sewage disposal truck into the yard and its work sometimes took even more time.

Conclusions:

• First, I don’t regret purchasing a submersible fecal pump, since I got the opportunity to periodically clean the cesspool of water on my own. The call for a sewage disposal truck is postponed until a very distant future, until the moment when circumstances force the pumping out of bottom silty sediments. But, judging by observations, such a need is not expected in the next few years.
• And the second one. Guided by own experience, I will take the liberty of giving advice - do not pump the cesspool dry with a sewage disposal machine while it is able to cope with water drainage on its own! I won’t let sewage trucks near my second, “working” well at any cost!

Equipment for autonomous sewerage It should serve for a long time, work flawlessly and not cause problems with breakdowns. How to decide on the model and buy the most suitable fecal pump with grinder? After all, the list of responsibilities of this equipment includes not only pumping aggressive liquids, but also processing large organic particles.

For fans of country life, we will tell you in great detail everything about the design features and guidelines for choosing the right fecal pump. With our help, you can easily find and purchase the optimal model with the required performance and excellent technical characteristics.

The article presented to your attention describes in detail the types of fecal pumps and outlines their differences in design and operation. For potential buyers, a rating of models in demand on the market is given. The information is supported by photographs and video instructions.

Industrial production Several types of similar technological equipment have been developed and are being released to the consumer market.

In particular, future users are offered:

• submersible devices;
• semi-submersible devices;
• external devices.

Each of the fecal models differs in technical capabilities and is designed for specific pumping conditions. In order to select equipment according to its merits, it is recommended to obtain information regarding the degree of contamination working environment, as well as information about the conditions under which the pump will be operated.

Fecal submersible pumps have found wide application in a variety of areas of the national economy. These same devices are actively used by owners of private country real estate

The submersible equipment is arranged in the form of a hermetically sealed structure, which, together with the electric motor, can be immersed in the thickness of the liquid medium. Semi-submersible fecal units are products in which only the pumping part is placed in the liquid.

Finally, external fecal pumps equipped with a grinder do not directly contact the liquid medium at all. Contact is made through a soft hose or a hard pipeline.

Private households for the most part do not have a connection to the central sewerage system. Waste from the toilet, kitchen, and bathrooms ends up in the waste pit on the site. The volume of the cesspool quickly increases and constant cleaning is required to prevent waste from flooding the area.

Sewage pump with grinder for – good decision for a private house or cottage where it is not possible to connect to a central pipe or the location of the house does not allow wastewater to be discharged away from the site. You have to periodically pump out the contents using a pump and hire a sewer truck.

Why do you need a fecal pump?

The scope of application of fecal pumps is quite extensive:

• for pumping street contents country toilet into the sump, located closer to the street, for ease of removal;
• for pumping waste and fecal water into a special machine;
• in public places - beaches, cafes, hotels, where there are kitchens and large food waste ends up in the drain;
• for cleaning reservoirs where there is a high probability of large soft objects getting in;
• draining areas or basements from wastewater after rain or snow;
• for pumping out city sewerage in case of blockage.

This is just a small list of capabilities that a submersible fecal pump can perform.

Pump operating principle

Sewage pumps with a grinder have different operating principles depending on the modification:

1. Submersible units protected by a waterproof case. They are assumed to be completely immersed in the working fluid. There is a sensor to monitor the wastewater level. The cutting mechanism processes and crushes large particles with a diameter of up to 5 cm into smaller ones.
2. Semi-submersible mechanisms assume the location of the motor above the wastewater. There is also a sensor that prevents the engine from touching the working fluid. The motor is not protected.
3. Surface fecal pumps with a cutting mechanism, the working fluid is pumped out through a special hose, which is inserted into a sump or cesspool.

Important! The most versatile and practical device is surface pump. It can be used in all situations on the territory of a residential building or cottage, be it pumping dirty water, fecal matter from a toilet, or draining an outdoor pool. Such models are least susceptible to contamination, so maintenance of the device will be carried out rarely.

Toilet pump device

Fecal pump made of corrosion-resistant materials. This is especially true for submersible models, which always operate in chemically aggressive liquids. Most often these are cast iron and stainless steel.

The pump has an oil chamber that protects the main working components from overheating. The oil does not need to be changed during operation - it is designed for its entire service life.

There is a cutting wheel with sharp knives for grinding large particles. Surface models have a pipe through which liquids are sucked in.

The main design detail is an electric motor. The devices are equipped mesh with a certain cell size so that objects larger than expected cannot get into the mechanism.

Surface pumps

External pumping equipment is capable of crushing not only soft objects, but also wood, plastic, and glass that have gotten inside. The more powerful ones also crush stones. The devices differ:

• power;
• shape;
• sizes.

The model can be selected based on the purpose for which it is purchased. The use of surface equipment is convenient because it can be moved if necessary and install in different places.

Submersible pumps

The main purpose of submersible sewage pumps is to clean septic tanks. Most of these models are automated and can be customized independent switching on according to a specific schedule.

If this is a pump for fecal matter in a public place, then it will need to be turned on several times a day so that the pit does not overflow and the smell does not penetrate into the room. Replaceable carbon filters are used to neutralize odors.

Sometimes submersible models with a chopper are used in agriculture. It is used to prepare raw materials for compost. A manure pump with a grinding mechanism crushes cattle feces along with straw and other vegetation, then pumps it into piles where the compost heap is located and organic fertilizer matures.

For industrial use, powerful models are needed, for example, mobile pumping station, which works for diesel fuel. The manure pump is installed on vehicle, most often on a tractor. Similar equipment makes people's work easier and speeds up the process of preparing fertilizer.

Important! Submersible mechanisms are more complex in design and require careful installation according to the manufacturer's instructions.

Which pump is more convenient in everyday life?

For domestic use, units are used that operate from a standard 220 V power supply. If there is only one phase on the site, then you can choose a model for such a case. A household fecal pump can operate from either a two-phase or three-phase network.

In order for the pump to cope with all tasks, the diameter of the mesh must be at least 3.5 cm. Larger is better, since children can throw anything into anything - clothes, toys.

For household use you can choose any model– submersible, semi-submersible or surface. It depends on where exactly the device will be used:

• if only for the toilet, choose a submersible model;
• if you plan to change the place - then superficial;
• if the plot or basement often flooded and the main problem is wastewater, then semi-submersible.

Judging by consumer reviews, they most appreciated surface and submersible models, which require less repair and are more versatile.

If the kitchen and toilet have the same drain, then you need to purchase a submersible model, because:

• the unit will not freeze while in the working fluid if you plan to operate it all year round;
• fecal pump with grinder for cesspools can be raised to the surface if necessary and inspect;
• the minimum power is enough to periodically turn on and clean the septic tank, which saves energy.

Sewage water equipment with grinder can also be used to pump liquid into compost heap, where the fermentation method can be used to prepare organic fertilizer for the garden. To do this, just add a concentrate of live bacteria. Liquids with chemical additives such as detergents and powders are not suitable for preparing fertilizers. Therefore, only fecal waste should be used.

Installation of a cesspool pump

For stationary use, the unit must be lowered into the pit along guides. It’s good if you plan to use the device when the pit is not yet filled, since it will require connecting the pipe to the outlet pipe, which is easier to do in dry mode. First, the submersible equipment is attached to, then lowered to the bottom of the pit, where the pipe connects to the pipe. The device is fixed by its own gravity - this is facilitated by the heavy cast iron body.

Surface models for pumping cesspools are not used in winter, as the liquid easily freezes and leads to equipment failure. Such units are useful in summer cottages in the spring and summer, when the temperature outside is above zero.

There is an option to connect the pump directly to the toilet. The equipment will crush the waste and send it to the pit. If the pump has a cutting mechanism, then a large diameter pipe will not be needed.

For connections between pump and plumbing equipment an adapter is needed. This model can be hidden so that it does not spoil the room or toilet. The temperature of the liquid should not be higher than 40 degrees.

Several types of plumbing equipment can be connected to one unit:

• toilet;
• bidet.

For hot drains, you need a different model that can withstand temperature up to 95 degrees. If you plan to live permanently, it is recommended to immediately purchase a universal device to which you can connect a dishwasher and washing machine. It will cost more, but it will be convenient to use.

Rating and prices

The rating of fecal equipment is headed by the German company Grundfos. Its products are in demand, despite high prices. Consumers prefer to give money for reliable technologies and durable materials so as not to be distracted by repairs during work.

Although in terms of repairs, the company is also doing well:

• spare parts are constantly on sale;
• work service centers who carry out repairs pumping equipment;
• In the event of a defective purchase, which is practically impossible, the company will replace the product.

More low prices and quite acceptable performance characteristics are offered by domestic manufacturers, namely the company Gileks. The company works with reliable materials and branded equipment, so the products are different good quality. In the event of a breakdown of pumping equipment, you can always repair or replace the product.

Here are some of the most popular models:

• Grundfos (SEG series). Fecal pump German manufacturer considered the most reliable. This is evidenced by consumer reviews and warranty statements. Made from rust-resistant materials - cast iron and steel. Immersion depth is 10 meters. Power reaches up to 2200 W. The price of equipment starts from 73,000 rubles. These are the most powerful models from the household series.
• Gilex (Fekalnik series). Household fecal pump domestic manufacturer– a universal device for a private home. With its help you can clean the septic tank, pump out clean water from a well, pump out dirty water After prolonged rains, water the garden. Works from a depth of 10 meters. The price starts from 6,000 rubles.
• Sprut (V1300D series). The maximum particle size that the device can pass through is 1 cm. It works from a depth of 5 meters. You can buy it for 9000 rubles. The fecal pump with grinder for the Sprut toilet is made in China, but is of good quality, as evidenced by consumer reviews.
• Herz (WRS series). The model can be used for domestic and commercial purposes. The case is made of stainless steel. The power of the device is enough to pump liquid over long distances. The cutting mechanism easily shreds fabric fibers, ropes, clothes caught in drains, and fecal matter. Supports high level performance throughout the entire service life. The cost of equipment starts from 17,000 rubles.

To choose the right equipment for home use, you need to know several important points:

• at what depth the pump will operate;
• estimated distance from the pump to the waste storage area;
• approximate volume of liquid;
• what size will the solid impurities be;
• what is the diameter of the pipe leaving the equipment.

You can determine the required working depth using the formula: pit depth + (distance to storage location divided by 10). Example: 7 meters is the depth of the septic tank. The distance of 20 meters to the sump, divided by 10, will be equal to 2. And 7 + 2 = 9 m. That is, you need a unit that will operate from a depth of 9 meters. Accordingly, it is necessary select device power with such performance characteristics.

Important! Pumps for pumping out cesspools help make life in a private home more comfortable, so it’s worth investing in purchasing a suitable model.

Fecal pump - expensive, but practical and reliable device. For correct operation, you must follow the installation rules described in the operating instructions. If connected correctly and operating conditions are met, you can count on a long service life without the need for repairs.

Fecal pumps, or as they are also called - submersible fecal pumps, are specially designed for pumping contaminated water with inclusions of various sizes. Here are some examples where they are actively used.

Pumping wastewater, fecal water, sewage discharges,
- pumping out the contents of cesspools and flooded basements - especially important for private houses and summer cottages in the absence of a centralized sewerage system.
- pumping out flood waters with a large amount of small debris - grass, silt, clay, etc.

The fecal pump does not have to be used only for heavily contaminated water - it is quite versatile and can be used, for example, to supply water from small pond, which is relatively pure, but nevertheless contains inclusions.

What is a submersible fecal pump

A fecal pump, like other pumps, consists of a housing, an electric motor and a working impeller, but its distinctive feature is the resistance of the housing to abrasive and chemical impurities, the presence of a grinding knife in front of the inlet, and fairly high productivity.

The body is usually made of cast iron or stainless steel. Sometimes, if it is a lightweight household option, it is made of high-quality wear-resistant plastic. The impeller and shaft of such a pump are also made of stainless steel or ordinary steel, but are coated with a special compound to increase abrasive and chemical resistance. The size and nature of impurities that may be contained in water are indicated in the specification (instructions) for each pump; these can be either solid or fibrous (grass, fibers of various lengths and nature) inclusions.

Fecal pumps are divided into the following classes:
- external sewage pumps – the pump is located on the surface, the pumped water is taken water is coming through a hose or pipe
- submersible fecal pump - its body is completely immersed in water.
- semi-submersible fecal pump - installed vertically, some models have special legs for installation.

By area of ​​application, domestic and industrial sewage pumps are distinguished. Industrial modifications have larger diameter passage, greater power and productivity, as well as a more advanced grinding system. Household models are more mobile, easy to install where necessary, convenient to use, and equipped with several degrees of protection.
