The circulation of coolant in the heating system occurs thanks to circulation pumps. The pumps are designed for water that is not potable.

Gilex company engaged in the production pumping equipment, produces a series of Compasses designed for heating systems.

Application and purpose

Gilex Compasses are circulation devices designed for heating and cooling, air conditioning, ventilation systems. The purpose of the units is to circulate the working fluid in closed systems. When operating the devices, pipes of a smaller diameter are used than with natural circulation. Ensure uniform temperature distribution in systems. The series of units is distinguished by a wet rotor and a three-speed motor. The engine houses a unit for manually adjusting the speed of the working fluid in a closed system.

Gilex Compass ensures heating of the heated room and uniform distribution throughout all parts of the working fluid circuit.

The presence of a wet rotor allows you to regulate the system. It features high performance, energy efficiency and low noise during operation.

Putting the pump into operation

Before connecting, the device is filled with water and air is pumped out. To release air, a bolt located on the rear of the motor is rotated. The air will begin to bleed. If water begins to flow out, it means the air has been released. The bolt returns to its original position. The valves on the suction and discharge sides open.

To switch the speed, use a speed switch located on the capacitor box.

Installation rules

Installation is carried out in a ventilated, warm room.
Installation is carried out upon completion welding work and cleaning the system.
Closing valves are installed at the inlet and outlet to the pump, this will prevent leaks and water drainage from the system when.
To prevent breakdowns, the device is installed above or near the pipes.
The device is connected to the pipeline so that the axis of the incoming and outgoing pipes coincide.
To ensure quiet operation and absence of vibration, the unit is not installed close to the knee.
The diameter of the pipe must match the diameter of the unit;
Installation is carried out so that the direction of the arrow on the device coincides with the direction of the working fluid;
The unit is installed taking into account accessibility if necessary.

Safety precautions

Before dismantling or installing the unit, it is disconnected from the network. Before dismantling the device, wait until it cools down.

When bleeding air, electrical parts are protected. To avoid damage, the pump is installed in a dry place.

The temperature range of the room is from minus ten to plus fifty degrees Celsius.

Problems with Gilex and how to fix them

Circulators are reliable, but minor problems occur. To eliminate them you need to know the cause.

List of problems:

When starting, the unit stops immediately. The reason is plaque between the impeller and the housing. The problem can be resolved by removing the plaque and unlocking the shaft;
high noise level. The reason is air in the system or high water pressure. Fix the problem by bleeding air from the system and reducing the fluid speed;
the unit does not start. The reason is that there is no voltage in the network, the capacitor has broken, deposits on the bearings have blocked the shaft. It is necessary to check the integrity of the cable and unblock the shaft;

If the operating rules are followed, the compass serves long years and does not require.

Gilex Compasses are distinguished by their reliability and quality. Positive reviews confirm the quality of the devices.

Operating restrictions
Before putting the pump into operation, you must carefully study the passport and strictly follow the installation rules.
The Compass pump is not designed to work with viscous and aggressive liquids, alkalis or acids.

1. The pump is strictly prohibited from being used without water. This is due to the fact that the pump is cooled by the liquid flowing through it. When used without water, the pump's ceramic bearings will wear out quickly. As a consequence, this will cause the impeller to stop. In addition, wear of ceramic bearings cannot be repaired under warranty.
2. In order for the device to operate without problems and noise, it is necessary to provide it with normal operating conditions, namely:

The pressure at the outlet of the water column must be at least 9 m.
Temperature - no more than +110 C

Main parameters of the Gilex Compass pump

The Gilex heating circulation pump can operate in some modes, switching between which occurs exclusively manually.

Advantages of working with such a switch:

Energy saving;
Reduced level of operational wear;
Minimum noise level.

Device installation

The Compass pump can only be installed in a well-ventilated and warm room. In cold conditions, the device may not work correctly or may not work at all.
It is important to note that the Compass pump can only be used when welding and other work on the heating system is completely completed.

The manufacturer recommends installing closed valves not only before, but also after the pump. This will help avoid water leakage if the pump itself is replaced.
The pipes must be installed in such a way that the pump does not experience pressure from them due to their mass. In addition, the pipes should not be initially under tension.

The Gilex Compass pump is installed directly into the pipeline. Thus, the axis of the circulation pump will be coaxial with the pipeline.
The compass is only allowed to be placed in a flat part of the pipeline. This will avoid unnecessary vibrations and noise during operation.

There is an arrow on the Gilex pump body that indicates in which direction the coolant will move. Therefore, the coolant flow must follow the direction of this arrow.

It is best to have the pump at hand or installed in convenient location. Thus, if necessary, he will always be there and you won’t have to waste time on preparatory work or repair.

The circulation pump is installed so that the coolant cannot damage the motor of the device.

Start of operation

Each Compass pump is equipped with a rotor that operates in water. The rotor is installed by the manufacturer in special bearings, so before starting work with the device, it is necessary to bleed air from it and pour coolant into the pump.

Important! When releasing air from the device, you need to be careful and attentive. It is necessary to ensure that water from the pump does not fall on it. electrical elements. This important point safety precautions.

Air is released from the pump as follows:
There is a bolt on the back of the electric pump motor that needs to be unscrewed.
You will be able to literally immediately notice that the air gradually begins to escape. As soon as all the air is released and water begins to flow out of the pump, the bolt must be quickly returned to its place, tightened tightly.
The valves on both sides of the pump must be opened.
During operation (depending on the system), the pump can become very hot in a very short time.

Remember! Pumping out air and turning on the pump should be done at low speeds.
For safe operation of the device, as well as for personal safety, it is not recommended to touch even the pump housing during operation. This will protect you from possible burns.

Speed setting

As already mentioned, the Gilex Compass pump operates in several speed modes. There are three of them. Switching between modes is possible thanks to a switch located directly on the body.

Before preparing the Compass pump for operation, it must be completely disconnected from the network. It is also important to ensure that an unauthorized person does not have access to turn the device on and off.
Once you notice that the pump has become very hot during operation and has reached its maximum operating speed, you must immediately turn it off and wait until it has completely cooled down.

Failure to follow these safety instructions will result in consequences and injury.
Subject to normal conditions operation, the device does not require repair or even maintenance for many years.
If Compass for a long time is not used, it may become blocked. But this does not mean that it can no longer be used.

The manufacturer offers an unlocking scheme that will allow you to get the most out of your device in the future.

Unlock scheme:

1. Turn off the pump, disconnect from the electrical network
2. Unscrew the valves on both sides
3. Unscrew (completely) the bolt for pumping out air
4. Take a screwdriver, insert it into the shaft, and turn it until the shaft turns freely
5. Now you can return the bolt to its place.
The Gilex Compass pump is strictly forbidden to be used by people who have no experience, people who have not been instructed, and also children.

The main reasons for the pump not working and options for eliminating them

1. The most common problem that a user may encounter is the device simply not starting. If the Compass pump does not start, the reasons for this may be:

No electrical voltage;
Lack of power supply;
Rotor blockage due to plaque;
Non-working capacitor.

Check the presence of power and voltage in the network, check the pump cable for faults.
Try to unlock the circulation pump using the method described above.
Try turning on the device at first speed.
If all else fails, contact service center for professional help.

2. Another problem that may arise is the high noise level of the pump.
The reasons for this may be the following:

There is a lot of water in the pump that it cannot handle.
Air was not completely released before operation and entered the system.

To resolve problems, the manufacturer recommends following these steps:

Set the minimum operating speed.
Bleed the system completely

3. Big level pump noise Compass. There can only be one reason for this:

The excess air that got into the system was, again, not completely pumped out before the heating circulation pump started operating.

To solve the problem, you need to take a screwdriver and pump the air out of the system. Then replace the bolt and try working with the pump again.

4. Another common problem is the situation when, after starting the pump, it immediately turns off without starting to perform its functions.
The reason for this is the layer of plaque that has formed between the rotor and stator. In addition, plaque can form between the device body and the pump impeller.

To fix the problem you need to:

Completely disassemble the circulation pump.
Rinse it thoroughly, getting rid of plaque.

Important! When cleaning the device from deposits, you must ensure that running water does not get on the electronic elements of the system. Before using the pump, it must be thoroughly dried.

Gilex circulation pump reviews indicate that users are completely satisfied with the functions that the device performs, as well as its high-quality, silent and efficient operation.
You can buy a Compass pump in any professional store or online store.

Circulation pumps Gilex Compass ensure accelerated movement of the coolant in the heating system, which prevents the water in the pipes from cooling until it returns to the boiler. This eliminates the need to reheat it. In addition, the settings ensure that the room warms up much faster with an even temperature distribution.

Technical Advantage of Jeelex Product

If we compare the design Compass with competitive equipment similar in action and purpose, with which this market segment is crowded today, you can see a certain superiority:

economical electricity consumption;
the presence of a three-speed special switch ensures low noise reproduction;
both the housing box and all nuts are made of materials that are not susceptible to corrosion;
air deflates easily because pumps have a corresponding built-in valve.

Models of installations of this line Gilex It is advisable to use it in relation to old-type communications, where the main lines consist of a pipeline of impressive diameter. It will not be possible to ensure natural, complete circulation without outside help. But this problem is completely solvable with this unit.

Circulating The device forces the coolant into the desired movement forcibly. Acceleration (speed) is calculated in such a way that the coolant in the system, when returning from the pipes to the boiler, has a maximum temperature. Thus, owners of premises (residential and non-residential) save money on heating.

Gilex Compass pumps are used for pumping hot water or coolant in heating systems. Moreover, these pumps can be used for transportation cold water in systems not associated with drinking water supply.

Design and operating principle

The main design elements of the circulation pump are shown in the figure.

The Compass pump, like most centrifugal pumps, does not have self-priming, that is, before starting it must be filled with liquid. When power is supplied to the drive motor 1, the rotor 2 begins to rotate, which is connected to the shaft 3, driving the impeller 4, which acts on the liquid, directing it from the suction channel 5 to the discharge line 6. The structural elements are located in a collapsible housing 7.

Installation and maintenance of pumps Compass

Circulation pumps may be installed in the following positions.

Do not install pumps in the following manner.

All circulation pumps must be primed before starting. To completely fill the pump, you can unscrew the plug.

Possible problems

Pump noise

The causes of noise may be:

Increased fluid resistance in the pipeline
Air in the pump

In the first case the noise may be caused by too much high speed currents, in this case, you can (if the system allows it) reduce the speed by switching the corresponding switch on the pump.

Also, the presence of air in the heating system can create noise. In this case, it is necessary to remove air from the system.

The second common cause of noise is the presence of air in the pump. In this case, you need to fill the pump with water, unscrew the plug, and wait for the water to flow out. When performing these actions, it is necessary to de-energize the pump and secure electrical connections from getting wet. Be careful the system may be full hot water. When working with the pump, generally accepted safety standards must be observed.

Circulation pumps are used for heating, air conditioning, water supply and ventilation systems. The units circulate liquid in the network. Thanks to this property, heat or refrigerant spreads throughout the system, maintaining the temperature.

A trusted equipment manufacturer includes the company Gilex, which specializes in the production of pumping equipment. The brand of circulation pumps is called Gilex Compass.

1 Purpose

Gilex Compasses are used for forced movement of liquid in the system (heating, water supply, air conditioning). The units do not have the functions of raising water to a height and increasing pressure. The devices are capable of increasing the speed of movement of the working fluid.

In Gilex heating systems, Compasses are used to move water from the heating boiler through the heating element into the system. This maintains and evenly distributes the water temperature in the circuit. Devices with higher power are used in industry, while devices with lower power are used for domestic needs.

2.1 How to deal with problems?

During operation, breakdowns occur that you can deal with yourself:

Noisy during operation. The reason is air entering the system or rapid fluid flow. To eliminate this, air is removed or the flow rate is reduced;
the device does not turn on. The reason is a broken capacitor, lack of voltage. To eliminate this, the integrity of the cable and the voltage level in the network are checked;
after startup, the device stops. Limescale– the cause of the problem. To eliminate this, wash the device.

2.2 Mark recognition

The units differ in cross-section and pressure. The first number in the model name means the cross-sectional size, the second means the pressure created. For example, circulation pumps Compass 32/40 have a cross-section equal to 3 centimeters two millimeters, the pressure is four meters, and pumps Compass 32/80 have the same cross-section, but the pressure creates eight meters.

Compass units are distinguished by high-quality manufacturing, reliability and wide model range. The reliability of the pumps is confirmed by reviews.
