centrifugal single -stage submersible pumps of the" b "EP" are designed to pump polluted fluids, sludge, soil, sand, gravel and other substances with abrasive effects, the parameters of which:
- impurities concentration - up to 20 %;
- the maximum temperature is up to 40 ° C (313 ° K)
- maximum density - up to 1,200 kg/m 3
- pH limits - from 5 to 8.5;
-the maximum immersion of the pump unit up to 10 m;
Pumps of this type can be successfully used in emergency situations to eliminate water from flooded rooms, construction sites, mining mines, sewage mines, etc.
The centrifugal single-stage pumps together with the electric motor form a general design. The rotor and stator of the electric motor are mounted in a special housing, which is washed with a pumped liquid and thus cooles. The electric motor is sealed with rubber "o" rings. Two mechanical seals are provided on the pump shaft, one of which is located inside the oil chamber, and the second is provided for isolation of the oil chamber from the fluid.
The pump is equipped with a filtering mesh that protects the pump from clogging. The dimensions of the net holes are 4 mm.
