Pumps designed for water supply systems with constant or variable flow with medium temperature not exceeding 100°C (80°C) and pressure not exceeding 0.6 MPa. Pumps are most often used in heating and cooling systems. The smallest in the series, the IPML 25/125 pump can also be used to charge solar systems. Circulating water pumps IPML 50/1100 and 50/2200 are intended for water containing non-abrasive and non-absorbent solid impurities of 0.27 kg/m3.
