APPLICATION
Type SE electric pumps for heat-supplying systems are a modification of horizontal, single-stage pumps with a double suction impeller. They are designed for water with temperatures as high as 180°C and with concentration of solid impurities of 5 mg/l or less, with their size of 0,2 mm or less.
DESCRIPTION
These pumps differ from D type pumps in that inoculated cast iron is used for the case, cover and the working wheel and that there is a cooling water jacket around the sealing units.
The main sphere of application is heat-supplying systems.
Normal operational conditions require a backwater of 100 m of water column before the impeller inlet.
