Циркуляционный насос EPA ESN32-6-180-1

The height of the system (building) does not matter, since the liquid that is pumped into the supply pipeline pushes the water in the opposite direction as well. Therefore, it is possible to use a relatively small pump power to ensure the circulation of the working fluid. In accordance with the name, such pumps are designed to ensure the circulation of the coolant in the heating system. This avoids stagnation and ensures the efficiency and uniformity of heat transfer; without the pump, the circulation intensity would be insufficient due to the high hydro-resistance of the system. A mandatory feature of the units of this purpose is the ability to work at a high temperature of the pumped liquid of the order of 95 C, or even more. Note that this allows the use of such pumps also in cold and hot water supply systems, however, it is unlikely that this can be called the best option - heating models are usually more expensive than other types due to high temperature resistance and performance, and these moments in the hot water circuits are superfluous.
