Forced movement of water in water supply and heating systems is provided using pumps. Reliable and effective work pump, when heating premises, supplying cold and hot water will provide all household needs, and in some cases, industrial needs.

Normal operation of the Wilo pump is possible only if the operating rules are followed, timely maintenance (preventive maintenance), high-quality diagnostics and repairs.

Operational Requirements

In order to avoid premature repair of Wilo pumps, the following should be adhered to:

• exclude idling operation (in the absence of water in the system);
• do not block the water flow when the pump is on;
• set the operating mode in accordance with the minimum and maximum capabilities of the equipment;
• follow the manufacturer's recommendations for permissible pressure in system;
• do not allow the coolant approaching the pump to heat up above 65 °C;
• avoid long periods of downtime;
• use filters to purify water circulating in the system.

If these rules are followed, the turned on pump will produce a uniform sound and maintain a stable pressure, which is evidence of its normal operation. Most pumps operate without repair for 5 years or more, until the main elements are completely worn out, provided that all operating rules have been followed.

Prevention

In order to avoid the need for repairs to the Vilo pump, it is necessary to carry out periodic preventive work. You can carry out simple maintenance of the device yourself, without resorting to the services of specialists. To do this, inspect the pump at least 4 times a year and, if necessary, clean it. As practice shows, cleaning is necessary after 2-3 years of operation, depending on the quality of the coolant and general conditions under which heating and water supply systems operate.

When inspecting the equipment, be sure to pay attention to the following points:

• no leaks at connections;
• grounding performance;
• absence of extraneous sounds during operation of the device (clanging, knocking);
• no vibration;
• pressure in the system in accordance with technical standards;
• dry and clean device body.

Wilo pumps, in most models, are reliable and do not require regular repairs. But prevention, provided that guarantee period expired, you can do it yourself.

For this you will need:

• spanner;
• Phillips screwdriver;
• flat screwdriver;
• cleaning brush.

Before dismantling the pump, water is drained from the system or the area is closed to dry disconnect the device. After which the pump is removed, and the following steps are performed:

Having completed these steps, the main disassembly is completed and the internal surfaces of the shell, impeller and rotor are cleaned of scale or dirt deposits.

Surfaces are cleaned using a stiff polymer brush with a small amount of cleaning agent containing hydrochloric acid.

In case of severe (sticky) contamination, it is permissible to use zero grade sandpaper.

The main malfunctions of Wilo pumps are wear of the support bearings. If such a factor is identified, it is difficult to replace them with your own hands, so it is better to contact a service center.

Before reassembly, all gaskets and seals are checked for cracks or tears. But since the pump has already been disassembled, it is advisable to replace them with new ones.

Basic problems and methods for resolving them

In cases where vibration appears during operation of the device, extraneous noise occurs, or the pressure in the system changes, you should determine the cause and, if possible, troubleshoot the problem yourself.

When turned on, the pump hums, but the shaft does not rotate:

• The shaft jammed due to prolonged downtime. Remove the protective cap on the motor housing and rotate the shaft using a flat-head screwdriver;
• if foreign objects get in, disassemble the pump and clean the impeller, after which replacing the cleaning filter, which is installed in front of the device;
• problems with power supply (insufficient voltage in the network).

When turned on, the device does not work:

• there is no voltage in the network. Electrical wiring and protective automation are checked;
• The fuse has blown. Replaced with a new one.

Automatic shutdown of the device after a short period of operation:

• accumulation limescale in the stator cup. The glass and rotor of the electric motor are cleaned.

The pump makes a lot of noise when running:

• dry operation with air in the system. Release the air and make sure the pump shell is filled with liquid;
• cavitation. The pressure in the fluid supply line must be increased.

Excessive pump vibration:

• critical condition of support bearings due to severe wear. The bearings should be replaced.

Reduced pressure and flow compared to technical characteristics manufacturer:

• power supply failure or phase change, which leads to a drop in power or reverse rotation of the impeller. Checking the phases (three-phase motors) and replacing the capacitor (for single-phase power supply);
• the pipeline has great resistance to fluid movement (hydraulic resistance). Clean (replace) the filters, check the shut-off valves, and increase the diameter of the pipes if necessary.

Automatic pump shutdown external system protection:

• malfunction of the electrical components of the device. Check connection terminals (oxidation, short circuit), capacitor (replacement), control unit.

Repair

It is better to have your faulty pump repaired at a service center if the warranty period has not yet expired. Some models are non-separable or partially disassembled, which implies repair work in the form of replacing entire units or the entire device.

In the absence of a warranty and the possibility of disassembling the pump, minor repairs are carried out independently.

Based on the above symptoms, the causes of malfunctions are eliminated and repairs are carried out if the design of the pump allows for its disassembly.

Operating elements of the control unit that can cause pump failure and must be replaced:

• capacitor;
• connection block (terminals);
• speed controller.

Since the capacitor has a small capacitance, its performance can be checked using the C-meter, which is built into the multimeter. If a discrepancy with the nominal values ​​is detected, this part should be replaced with a new one. It is important not to confuse the polarity of the connection and check the voltage matches. In a conventional single-phase electric motor, capacitors are installed that are approved for connection to a network of up to 450 V.

If the speed controller breaks down, it is replaced with a new one, observing correct connection terminals

The terminals should always be clean, dry, without signs of overheating or carbon deposits. If the above problems are identified, they should be replaced with new ones, similar ones or the same ones if possible.

During post-warranty operation, problems with the support bearings are possible. It is better to replace them in a specialized workshop.

To prevent scale formation on the impeller and silting of the stator cup, install high-quality filters and use the prepared liquid in closed heating systems heating. If these conditions are met, the pump pumping liquid will operate in ideal conditions and will not cause problems with repairs for a long time.
