Dacha water supply and country house equipped with wells or boreholes. A submersible pump for a well must meet certain requirements. Depending on the lifting depth, required performance and pressure, a centrifugal or membrane (vibrating) apparatus is selected. Which mechanism to use in a particular case depends on the quality of the water and the financial capabilities of the owner. Of all the models, submersible well pumps are considered the best.
How to correctly calculate and choose a device
Creating an autonomous water supply system using a well begins with measurements:
- The depth of the well is determined by lowering the load on the cord to the bottom and is checked against the passport data.
- The static level is determined by lowering the load to the surface of the mirror after prolonged filling. In the morning or after a long absence of swinging, the maximum filling of the chamber is determined.
- The difference in levels will give the depth of the water layer.
- Debit – filling the chamber per unit of time. This value determines the performance of the pump, the possibility of long-term swinging without draining the submersible pump.
In addition, you will need to know at what distance or height the water will be supplied to determine the pressure. Continued use of the raised agent is important. The presence of a storage tank will allow you to turn it on less often submersible pump for a well. During startup, the equipment experiences increased loads. Need to know chemical composition and suspended matter content in water.
Advantages and disadvantages of submersible pumps
The main difference between a well and a water well is the depth of the water horizon and the size of the pipe vent. Wells are built with a larger chamber, and the diameter of the pump does not limit the choice. But the well may have a lower flow rate of water, and the productivity of the device is limited.
The water level in the well varies with the seasons. In order not to pull sand into the pump at a level of 15 cm to the bottom, you need to install a metal fender board along the cross section of the well, leaving a gap along the contour. Under the sheet, grains of sand will not rise, and the water will always be clean.
Surface or submersible pumps for wells, which is better is decided in specific conditions. The most commonly chosen submersible apparatus is:
- the equipment is underwater, does not require filling, and is ready for use at any time;
- the engine is water-cooled and does not overheat even during long-term operation;
- the ability to install filters on the suction pipe protects the working mechanism from clogging;
- the use of automation ensures the supply of water as needed without human intervention;
- Dry running locks will ensure the safety of the equipment.
The more modern the device, the more automatic circuit and safety interlocks it has, the more expensive it is. Everything for wells is more expensive than surface ones. This is justified: their service life is longer, reliability is higher, and no special room is required to operate at zero temperature. However, the sealed housing cannot be repaired at home, and the filters in the inlet pipe must be regularly replaced.
Materials that are not destroyed by corrosion are used to make the pump housing. High-quality plastic works in water no worse than stainless steel.
It is important to choose a submersible pump for a well with automation in order to minimize operation control. In this case, the device can be built into a water supply and heating circuit. The automation system will give a signal to turn on the make-up when the level or pressure in the system drops.
When installing a pump, it is important to know the water flow into the receiving chamber of the well. It is dangerous to choose a level below the submersion of the pump; the device must always be under the fill, lowered at least 30 cm deep. Therefore, the best submersible pump for a well is one that provides the required flow, pressure and is always under fill.
Choosing a circulation or vibration pump depends on the nature of the work. Typically, a submersible pump is selected for a summer residence based on operating conditions. An inexpensive membrane apparatus works periodically and only in the summer. The operation of the unit is accompanied by noise; vibrations in contact with the walls of the shaft can contribute to destruction. A layer of silt forms at the bottom of the well. If the price of a submersible pump for a well is not main criterion– it is better to choose a circulation pump.
An incorrectly selected pump can lead to the appearance of quicksand, raising the bottom, and lowering the surface. Depressurization leads to the appearance of an oil film. Removing the consequences is difficult and requires large material costs.
Choosing the best submersible pump
It works on the “set it and forget it” principle. DAB pump Divertron 1000. One device replaces the storage tank, sold with built-in automation. The pump supplies water 45 meters horizontally, productivity 0.6-5.7 m 3 /hour. When you open the tap, the pressure is adjusted. The device pumps water and sand and can drain the pit if necessary. The cost of the device is about 20 thousand rubles.
Turn on the equipment only through a voltage stabilizer!
The Grundfos 3-45 A pump also belongs to the premium class. It is used to organize water supply for a country house. The pump operates automatically; an accumulator tank is required to raise water to the second floor.
The PROF 55/35 A water cannon costs half as much as famous brands, but its functionality is good. The pump can only be used to lift liquid. The water supply scheme is being decided circulation pump. The dry running mode is excluded, a float switch is used.
The submersible pump for the Aquarius-3 garden is the best solution. Low productivity is compensated by low cost - only 2 thousand. The submersible pump runs for 2 hours, then requires a rest of 15 minutes. To fill the tank for watering plants, it is used more often than other devices. Its advantage is ultra-high reliability. Operates without repair for up to 8 years.

If the private plot of land on which a residential building is built or is just being built is located at a considerable distance from centralized communications, then its owner will certainly install an autonomous water supply system. Without such a system, it will be impossible to create the necessary level of comfort for living in a suburban building. At the same time, many owners, before starting construction of a water supply system, want to know whether it is possible to use a drainage pump for water supply. They may have such an interest various reasons. For example, this equipment has already been purchased previously or there is an opportunity to purchase it at a lower price than it is sold on the market, and for ready-made solution You can contact iqterm.ru for help
What is a drain pump
The purpose of any drainage pump is to pump out water, which may have varying degrees of contamination. Such equipment differs in size and characteristics. In most cases, these devices are capable of raising water to a height that does not exceed 10 m. At the same time, in the horizontal direction they are capable of moving it up to 100 m. These are two very important characteristics that play a big role when choosing a unit.
In most cases, this equipment is purchased when it is necessary to carry out the following operations:
- eliminate the consequences emergency situations(water pipe break);
- remove flood waters that have accumulated in basements and ground floors buildings;
- clean swimming pools and other artificial reservoirs from aquatic environment with a certain degree of pollution;
- organize the supply of liquid for the operation of small fountains;
- watering a summer cottage with various plantings.
More pumps drainage type can be used to create drip irrigation. In addition, they are used to remove water directly from land plot, if it is flooded, for example, during a spill of natural reservoirs.
Types of drainage pumps
Manufacturers produce the following main types of this equipment:
- Submersible drainage pumps that sink to the bottom of a container, well or other object. They are often used on suburban areas, as they are easy to use, at an affordable price, easy installation, which can always be done on your own.
- Surface drainage pumps, usually installed near some object from which water needs to be pumped out. They are always equipped with hoses. It is these elements that are immersed in water.
When choosing a drainage pump, you need to consider their advantages and disadvantages. This will answer main question this article, as well as choosing the right equipment.
Features of submersible drainage pumps
Submersible units are small in size and weight. They can be operated for a long period, but with periodic stops. In this case, there is no need to carry out for such units Maintenance. In most cases, they have high productivity, which can reach several tens of cubic meters. m per hour. At the same time, such equipment is reliable, as it is equipped with protection against drying, presented in the form of a float element. Apart from this, they are used to move both contaminated and clean environments. This allows them to be used for organizing water supply on private territory.
Despite the numerous advantages of submersible pumps, this equipment also has disadvantages. Among them, we can highlight the fact that well units are not capable of creating strong pressure. Such equipment raises water to a maximum of 20 m. Moreover, most models average height the distance to which the medium can actually be raised is only 10 m. In addition, you need to constantly check the distance from the pump to the bottom, for example, of a well, so that contaminants are not sucked in along with the water if the device is used for water supply.
Note! Minimum distance to the bottom should be 800 mm.
Features of surface type drainage pumps
The advantages of this equipment include the pressure power, which is higher than that of submersible units. Such devices are capable of moving water several tens of meters. Surface pumps can be installed in the house, which eliminates the need to lay an electrical network, for example, to a well. In addition, such equipment can be operated continuously, thereby ensuring pumping of water into required quantity or its supply for different needs.
The disadvantages of surface drainage pumps include the impossibility of using them in wells in which the water surface is located below 8 m. A disadvantage is also the high noise level during operation. Therefore, it is best to place them in a separate special room or even in an extension to the house. In this case, a person needs to know the operating features of the pipeline through which the aquatic environment is suctioned.
Organization of water supply using a drainage well pump
First of all, distinctive feature This type of equipment is used to lift water from wells that have a shallow liquid surface level. At the same time, such devices are not designed for continuous operation. They need to be turned on only when necessary for a relatively short period.
If the site needs to organize a periodic supply of clean water from a well, then a drainage pump can be used for water supply. Such equipment is suitable for a summer residence. It can also be used for watering the area where the cottage is located, where people permanently live. However, a well drainage pump is not suitable for organizing the water supply of a residential building, since no one will be satisfied with water interruptions, and they will certainly have to deal with them due to the characteristics of the equipment. Moreover, these devices in most cases have low pressure. This will not allow them to be used to supply water above the first floor. They will also not be able to provide required pressure at several water points at once. Of course, when choosing such equipment, it is necessary to take into account the features of the specific water supply system being created.
The advantage of a well drainage pump is its simple installation. Simply immerse the device in water and connect it to the power supply. At the same time, it is advisable not to lower it to the very bottom so that it does not suck up solid particles and various deposits along with the clean liquid.
Conclusion
A drainage pump can be used not only to pump out contaminated water from various objects and containers, but also to supply clean liquid from a shallow well. Such equipment is ideal for watering the site. With its help, you can even supply liquid from a well to a nearby one. cottage. The device allows you to organize a good temporary water supply for a dacha or a permanent residential suburban building under construction.
Many owners of country and private farms not connected to a centralized water supply are familiar firsthand with the problem of supplying water to their home and garden plot.
The “Malysh” submersible pump will help partially solve this problem; although it is not a powerful device capable of pumping water from artesian wells, it can cope with supplying water from wells, shallow wells and open reservoirs.
For those who are just planning to arrange autonomous water supply, as well as users pumping equipment It will be useful to learn about the device, operating principle and operating rules of the unit. We will describe in detail how to install the “Baby” in a well and ensure its uninterrupted operation.
Submersible pumps of the “Malysh” series are produced Russian enterprise Livgidromash, whose history goes back nearly seventy years. During this time, more than three million units of various pumping equipment rolled off the plant's assembly line.
The use of a filter will not only extend the life of the unit, but will also ensure the supply of higher quality water, purified from any impurities.
Malysh pump maintenance
In order for the pump to serve for a long time and properly, it is necessary to comply with the operating and storage conditions recommended by the manufacturer. In this case, the manufacturer guarantees its normal operation for two years. The pump does not require complex maintenance and care, and simple rules It won't be difficult to do.
After the first installation of the device in the well, you need to let it work for one or two hours, and then remove it and carefully inspect the body and components to detect any malfunctions. If everything is fine, then the vibration pump can be put back in place and used further, leaving it immersed in water for a long time.
Periodically, at least once every three months, and if possible, then every hundred hours of operation, the unit must also be inspected. If traces of friction are found on the housing, it means that it was installed incorrectly and during operation came into contact with the walls of the water intake excavation.
To avoid this, you need to set it level and put an additional rubber ring on the body.
If the inlet holes become clogged, they must be carefully cleaned without damaging the rubber valve. For cleaning, it is best to use a tool with a blunt end.
If the pump is not used in winter, it must be removed from the well, washed and dried thoroughly. When storing the unit, place it away from heating devices and also protect from exposure to direct sunlight.
If, while following the manufacturer's recommendations, a breakdown occurs due to reasons beyond the user's control, the pump should be taken to a repair shop. service center. A list of popular breakdowns of the “Baby” pump and ways to eliminate them are described in.
Submersible pump “Baby” - convenient and inexpensive household appliance, easy to use and easy to maintain. Of course, due to its small power, it is not capable of providing a full water supply to a private home, and, in fact, no one sets such tasks for it.
The inexpensive vibrator is perfect for seasonal use. He will become a real assistant summer cottages. Thus, with the help of “Kid” you can organize watering of plants and water supply from wells, wells or open reservoirs.

A drainage pump for a well is used quite often. There are drainage pumps for pumping water, and there are drainage pumps for pumping water.
Therefore, you must first understand what needs to be done and then make a choice. After all, there are quite large and powerful units.
If you have large system, then it is likely that you will need not just a pump, but a drainage pumping station. Therefore, it is necessary to decide immediately on the scope of work. Today we will deal with the question of how to choose a drainage pump.
We decide on the tasks and choose
A well drainage pump is often used for pumping. They are used in cases where well water does not have high degree pollution.
Here the question will also arise about the volume of water. After all, there are low-power drainage pumps that are not able to withstand heavy loads, but nowadays there are already models that provide a touch sensor for the drainage pump.
These are more powerful units, but accordingly their price is much higher. Let's consider the application features, types, as well as the pros and cons of these devices.
Application of drainage pumps
Let's immediately look at what a drainage pump is, what it is and where it is used.
Such devices are very useful under the following circumstances:
- If it is necessary to pump out water after accidents,
- When the level groundwater rises high enough
- In basements and basements when flood waters accumulate,
- In case of prolonged and heavy rainfall,
- To clean artificially created water bodies, for example, swimming pools, they are cleaned using drainage pumps to meet hygienic standards,
- To organize irrigation large areas by drip,
- For decorative fountains drainage pumps are used to supply water to them. A drainage pump with a chopper is often used here.
Classification of drainage pumps
Now let's see how to choose the right one. Now let’s decide what the pump is needed for and where it should be used. You can also see everything in the photo. Such devices can be divided into two main groups.
Submersible drainage pumps
These devices are placed at the bottom of the object being cleaned before use. They are quite popular among summer residents and owners of private houses, since the use of such devices is not difficult, they are easy to install and replace yourself.
Among other things, submersible pumps do not have very high cost, which is also their strong point. Depending on the principle of operation of the devices, they are distinguished:
- submersible type,
- Submersible vibration pumps.
In addition to the characteristics already listed, submersible drainage pumps have other features:

Surface Drainage Pumps
This is a non-submersible drainage pump. The video in this article will show you how it works. Such devices are not lowered entirely, but only the hose is placed in the water. They have their positive and negative sides.
The advantages of surface devices include:

Drainage pump for a well: how to install correctly
Installation and operation are quite easy. But for proper operation device and its long service The drainage pump must be installed according to certain rules.
After purchasing and unpacking the purchased equipment, you must check whether the contents correspond to the package, and also pay attention to Special attention instructions included with this model. It is very important to study the existing limitations in the use of the purchased type of pump.
You can only make up general instructions which can be used to guide you when installing a drainage pump:
- A pressure line is connected to the pressure pipe, which can be a hose or pipeline, after which it is secured with the existing connecting parts.
- If there is a pump in the design float switch When using the pump permanently, a check valve is installed on the pressure line.
- The device with a three-phase motor is checked to ensure that the direction of rotation is correct. To do this, the pump is installed on a straight surface, it is turned on and immediately turned off. During this process, the direction of rotation of the shaft is monitored:
- clockwise - correct connection,
- against - the phases need to be swapped.
- For a device connected to a pipeline, the correct direction is checked as follows:
- connect to electricity and measure the flow,
- turn off the power, swap the phases and do the same as described in the first paragraph,
- The supply power in the first and second cases is compared, from which the correct phase connection method is determined.
- The device is placed in a vertical position with the pressure pipe facing up.
- The pump is lowered to the bottom of the well.
Using a sump pump to clean a well
In the process of selecting the appropriate type of drainage pump, it is very important to carefully study the instructions supplied with the device, since certain models can only pump clean water. At the same time, there are pumps that work well with contaminated water, including those containing small inclusions and fibers.
Attention: When the well for a long time has not been cleaned, it is better to give preference to a drainage and fecal pump that can pump water with heavy contaminants. Such devices contain cutting or crushing wheels, which crush large inclusions during operation.
For easier well cleaning, it is better to use drainage pump models equipped with a float. Usually this role is played by a certain switch that floats on the surface and turns off the pump when it reaches the bottom.
Otherwise, the operation of the drainage pump must be constantly monitored to avoid overheating of the engine, since the water in which the unit is immersed cools it.
A person does not need to dive into the well on his own; the drainage pump works automatically, but it must be configured correctly:
- First, the pump is immersed to a depth of 1 m without reaching the bottom,
- The device turns on, as a result of which the water is cleared from dirt,
- Further pure water enters the well under pressure, which leads to the destruction of silty growths at the bottom,
- During operation, the pump periodically rises to the surface and its filter is cleaned. These steps are repeated until silt deposits appear on the filter.
Attention: In some cases, after major cleaning, the drainage pump is left in the well, which allows it to be kept clean. At the same time, clean the filters of the device every six months.
- For capital cleaning work It is better to use a powerful pump, but a less powerful device is also suitable for maintaining cleanliness.
- Recently, the following practice has been very often used: the well is cleaned with a powerful pump a couple of times a year. The cleaning itself usually takes about a week, after which the pump is stored in a dry, clean room.
The use of a particular model of drainage pumps depends primarily on specific circumstances: the degree of contamination, the depth of the well, as well as other conditions. Depending on what characteristics a particular pump is endowed with, its cost will also be determined.
All the work is done with your own hands, so there will be no costs. Before purchasing, the instructions must be fully studied and after that you can make a purchase.
For any summer resident or owner of a private house, solving the water supply issue is a priority. Most optimal solution This problem is solved by drilling on your own site - in this way you can provide yourself with a supply of clean, fresh and non-chlorinated water throughout the year.
The essence of the artesian mechanism is that, thanks to the pressure created by the aquifer, water flows outward. However, it is very rare that, without outside help, the flow itself rises above ground level, as they say, in full swing, because the pressure may be weak, and the depth of the aquifer may be too great. In most cases, it is necessary to “help” the flow of water to rise to the level we need, and for this purpose it is impossible would be better suited deep well pump.
What is a deep-well pump and where is it used?
Submersible borehole pump- this is special hydraulic device, designed for pumping water whose level is located below its level. Naturally, devices of this kind began to be used for supplying and transporting water from underground sources of various types.
The only conditions that such a source must meet are that its depth allows a deep submersible pump to be completely immersed in water and the width of the well must be no less than 80 m. Unlike pumping stations, they practically do not create noise that can disturb the comfort of the residents of the cottage, provided that these devices have sufficient power to cover not only the needs of drinking water, but also to supply the required volume of process water.
In addition, an important advantage of deep submersible pumps is that they are self-cooling systems capable of lifting water (even with gases dissolved in it) from great depths. That is why, most often, such pumps began to be used in artesian wells. By the way, the division of pumps into “borehole” and “well” is very arbitrary - it’s just that the latter are more “tailored” for working with water containing a large number of all kinds of impurities, and the former are best used for pumping contaminated (various colloids) water.
What types of deep-well submersible pumps are there?
Screw pumps - the mechanism of action of these devices is to create a powerful pressure of water by displacing it with metal screw rotors rotating inside a stator that has the appropriate shape. Thus, the liquid moves along the axis of the screw in the chamber created by the body and screw grooves.
Centrifugal pumps - operate by creating a turbulent flow that pumps water from an aquifer at high intensity. That is, in pumps of this type excessive pressure occurs, due to the presence of which a certain volume of water rises through the pipeline. Following one such cycle, another immediately begins.
Vortex pumps - pump water using two special impellers, which have radially arranged trapezoidal blades located strictly at a certain angle. Taking into account the fact that this type of vortex pump constantly consumes air, throughout its operation the impeller mixes water and air masses. This leads to the formation of a vacuum in the pump chamber and a vortex, which promotes the suction of water. The vortex pump is one of the most complex in terms of design, but at the same time one of the most powerful devices of this kind. So, if it is necessary to pump large volumes of uncontaminated water, then you should pay attention to the vortex pump option.
Vibration pumps - their operation is ensured by the movement of a piston, which drives alternating current. In fact, a hydraulic shock occurs inside the pump chamber, leading to a rise in the water level. Easy to use and very reliable.
Naturally, anyone who wants to purchase a submersible well pump has a reasonable question: what type of unit should I choose? It should be noted that this question is not as simple as it seems. In order to actually implement right choice pump for an artesian well, it is necessary to carefully study a number of characteristics of a specific source from which water extraction is actually planned.
Advantages of using deep well pumps
The disadvantages are that the service deep well pump somewhat difficult. That is, in order to carry out the necessary procedures for caring for the pump, it must be removed from the source and then put back in place. In addition, such a pump cannot pump all the water. The concentration of mechanical impurities of transported water should be no more than 100 mg/l (0.01%).
A few words about the features of installing deep well pumps
Nowadays, the installation of deep-well pumps is becoming more and more popular, since, even despite its relatively high price, the use of submersible wells very quickly pays for itself. Although, for household needs The simplest well, which will be located at a depth of no more than 20 m, is quite suitable.
In the event that the owner of the site is unlucky and the aquifer is located at a depth exceeding 20 m, it will be possible to ensure autonomous water supply only with the help of special multi-stage modifications of these units.
What should you pay attention to when choosing a pump first?
In order not to regret your purchase (note that even the simplest deep-well pump costs a lot), you need to objectively evaluate the following points:
- How deep the well is, how high the water “stands” - this is what you should focus on as much as possible. It is not difficult to recognize them, since these parameters are necessarily indicated in the source’s passport, which is issued immediately after completion of its drilling. If for some reason they are unknown, then you can find them out yourself by using an ordinary rope with a weight - simply by measuring the length.
- How much water will need to be pumped? Naturally, to ensure drinking water even big family a much smaller volume will be required than, say, to irrigate agricultural land. Based on these parameters (to a certain extent, others are also taken into account), the required power of the installed pump is determined.
- Well flow is a concept that is characterized by the amount of water that the source is able to produce over a certain period of time. Naturally, this value is determined relatively. To do this, you need to use a powerful pump to pump out all the water from the well and measure how long it takes to do this. Afterwards, the time during which the water level in the well is restored is calculated. Then the second number is divided by the first, and the resulting result is the approximate flow rate of the well; you can safely rely on this value when choosing a pump.
- The pump pressure is also very important characteristic. It is determined as follows - it is necessary to add 30 to the well depth (in meters), and then increase the resulting number by another 10%.
- Well diameter.
- Price.
- Manufacturers.
It should be noted that, despite neither the quality nor the cost of the deep-well pump, the presence of abrasive particles in the transported water poses a huge danger to this device. And they are found almost everywhere, especially in sandy areas. It is for this reason that if the owner wants his pump to serve him faithfully long years, then he will install a special filter on it that retains solid inclusions. Another, more reliable protection option is to install a special floating suspension and apply a special wear-resistant coating to the impellers.
