Circulating pump for heating systems, UPR 20-35

Circulating pumps of the UPR series are circulating pumps with a "wet" rotor and with threaded connecting pipes. Application: Pumping of the heat carrier in one- or two-pipe heating systems or hot water supply, with a stable or slightly variable flow rate. Working fluids are pure water of low stiffness, low-viscosity, non-aggressive and non-explosive liquids without solid or long-fiber inclusions, as well as impurities containing mineral oils. Features: Pump housing material - cast iron; The maximum temperature of the coolant is + 110 ° C; The maximum system pressure is 20 bar; The maximum permissible ambient temperature is + 40 ° C. Hydraulic characteristics of pumps of the UPR series: Characteristics: Total head (m): 32 Maximum power (kW): 1.3 Maximum capacity (l ~ min): 100 Maximum working pressure (bar): 20 Maximum current (A): 5, 8 Weight (kg): 8,6 Mains voltage (V): 220/230
