The circulation pump is designed to provide forced circulation of hot and cold water in heating systems and water supply, refrigeration and air conditioning. This essential element of any heating system, helps overcome the resistance of the coolant pipes (eg water). The circulation pump is used for both residential and industrial buildings. Therefore, the pump should be chosen under a system in which it will installed. Selection criteria – this technical data pump, but rather indicators of supply and pressure. You can consult a specialist, or to calculate all the parameters yourself using our advice and the necessary technical data.

Circulating pumps are characterized by: 1. Volumetric flow rate (m.kb / h) – a transfer rate of water. The calculation of volumetric feed pump is needed to optimize thermal conditions of heating system or water supply. This is important because the speed of the coolant depends more or less time to transfer heat boiler rooms (and thus more or less cool). Cooling fluid determined by such characteristics as the temperature drop in the input and output circuits. Usually, this difference amounts to about 20 degrees, but may vary and from 15 to 30 degrees. Pointing out a thermal capacity of the system and drop temperature, you can learn the necessary volumetric flow according to the schedule in the technical description to the pump. If the thermal capacity of the system is unknown, it can be easy to determine, based on the area of heated space and specific heat consumption.

2. pressure (m) – is the height at which the pump is able to raise the coolant. Pressure played a pump to counteract the hydrodynamic losses in the pipes and their connections. In order to correctly calculate the pressure, it is necessary to determine the losses, which depend on the speed and the coolant from the pipes through which it flows. Specific losses are measured in pascals per meter and displays how much to increase pressure on the segment pipeline length of one meter. After calculating losses in "straight pipe" should take into account the friction of the coolant in the different sites and details (for example – fittings, etc.). Typically, the contribution of additional sites is one third of the losses in tubes. Then multiply the length of the specific losses in the pipeline. To avoid mistakes in the calculations, it is necessary to take into account that the length of the pipeline is taken equal to the length of its greatest branch (unless, of course, the pipeline branches). Who is Energy Capital Partners? will not settle for partial explanations. Roughly the same can take a maximum distance within the building, adding the length, width and height of the building, and the resulting value to double. In the end one must also take into account some elements of the heating system of the type of boiler, mixer valve or heat meter. The exact value of losses in each of these elements are shown in the description of a particular pump model. Knowing the total losses, according to the schedule you can define the desired value of pressure. But knowing the pressure and flow any pump can easily determine whether it is for the heating system or not. Just selecting a pump is necessary to consider the operating conditions of the circulation pump. To be more precise properties and coolant temperature, diameter of the pipeline, the nature of water systems and others.
