Pump circulating: installation, prices, testimonials, choice

Most often, heating systems are fully functional only when the circulation pump is installed. The price of such equipment will be mentioned below. It is also called a pomp. The device is necessary to maintain the desired level of liquid head in the heating circuit. This is its purpose, which is expressed in keeping the pressure at the desired level, thereby the coolant overcomes the hydraulic resistance, moving the water along the contour. The installation of the circulation pump can provide for the presence of several units of similar equipment in the system. One unit is installed in the boiler, while the other one is installed in the heating circuit. If the system has a well-functioning circulation pump, it is not necessary to place the boiler at the lowest point of the circuit.

How to choose a pump

It is important to correctly select the circulation pump, it must meet certain requirements. Among them, one should emphasize pressure, as well as productivity. The last parameter indicates how productive the equipment is. This characteristic should be calculated with the condition of minimum utilization of the device. Among the additional requirements can be identified working conditions, which are expressed in the volume of the heated room. It is important to take into account the type of liquid, the diameter of the pipes, as well as the temperature of the coolant and the environment.

Considering external aspects, it is necessary to pay special attention to the noise level during the operation of the device, the dimensions of the device, as well as the complexity of the service.

Selection of equipment by external factors

If you select a circulation pump, it is important to take into account the fact that external conditions will influence its operation. The amount of heat that is needed to heat the room will depend on the temperature of the environment. In some cases, this factor affects the operation of the device itself, it is expressed in the fact that the frozen equipment will not function as efficiently as it is heated up.

If the unit is incorrectly selected, the pump may start to overheat, this occurs when it can not cope with an excessively high load. Before installing the circulating pump, you must determine the parameters of the heating system and boiler equipment that determine the characteristics of the pump. With a large pipe diameter, there will be more water in the system, and the pump must be more powerful. Among other things, the heat carrier, which consists of a non-freezing liquid, has a viscosity that differs from the viscosity of water. This indicates that the pump should be more reliable and productive.

Additional recommendations for your choice

When choosing a circulating pump for water, it should be noted that the equipment can operate in tandem with a natural circulation circuit. If these conditions are met, the load on the device can be very high. That's why in this case, experts recommend choosing a pump with high capacity and pressure.

Choosing a device with insufficiently powerful indicators, you may find that the unit will become bad "push" the system, the radiators will only heat up a little. The pump under such conditions often overheats, and then completely burns. It is not recommended to install a 1-inch pump in a 1.25-inch pipe through adapters. At the same time, the necessary pressure may not be provided.

Customer feedback on pumps from different manufacturers

A circulating pump, the installation of which you will be done by yourself, must have good quality, and it is important to pay attention to the manufacturers. The models differ only in terms of their service life and the degree of reliability. As for the characteristics, almost all the variants of the described pumps are similar to each other. The most common brands on the market of the corresponding equipment are: Wilo, Grundfos, Wester, Speroni. The first two brands are the most reliable, they are characterized by quiet operation and durability.

Make sure that the equipment works, if it is manufactured by these manufacturers, you can go to the device at 10 centimeters. According to experienced users, the products of these companies work for years and does not require the need for repairs. But these devices have one big minus, which is expressed in high cost, the price will be twice as high compared to products manufactured by other well-known companies.

If you want to save, you should consider other of the listed brands, they produce products that are considered average in terms of quality and price. This is the opinion of consumers. Work equipment will be good, and problems can arise only in rare cases. If you need a circulating pump, the installation of which will be done by you alone, you should not, wanting to save money, purchase Chinese products. In the opinion of the owners, sooner or later, such devices start to make noise, the rotor is diluted, the pump breaks down and burns. On the timing of exploitation can not be anything. Users emphasize that Chinese-made pumps can only work for 2 months or up to 2 years. The only advantage is the affordable price.

Installation

A circulating pump, the installation of which will be carried out by you yourself, is ready to serve the entire service life, if the location of the tie-in to the pipeline is correctly determined . The master must select the position of the aggregate in relation to the horizon line. The shaft of the electric motor must be located strictly horizontally. Otherwise, there may be air jams that leave the bearings without cooling and lubrication. Equipment under such conditions is quickly worn out and will fail. Looking at the pump housing, you will see an arrow that indicates the direction of the coolant in the system.

Need to use a filter

A circulating pump, the installation of which must be carried out according to the technology, functions effectively in tandem with the mudman, whose task is the filtration of the coolant. This addition is capable of retaining sand, abrasive elements and scale. If dirt gets inside the pump, the impeller and bearings may be destroyed. Due to the fact that the diameter of the frame for installing the pump has an impressive size, it is acceptable to use a traditional coarse filter. The keg, which is necessary for the collection of suspended matter, must be directed downward. This will eliminate the possibility that the filter will act as an obstacle to water circulation.

Cost

The circulation pump, whose price is 3600 rubles, is best placed on the return pipeline, after the expansion tank membrane. Therefore, the device must be in front of the heating boiler.

Conclusion

When adjusting the system, it must be remembered that the duration of the work of plastic parts and bearings will depend on the water temperature level. Whatever it was, the system needs a circulation pump, the pressure with it can be normalized and returned to the template value.
