VERTICAL OPEN WELL PUMPS
Wet installation in stationary and transportable design. Submersible, single or multi stage, radial split casing. The individual casing parts are sealed by O-ring. In contrast with typical drainage electro pumps the motor is bottom part of assembly. This construction has advantage where ambient temperature is high.
Three-phase electrical motor is used.
Fitted at pump and motor end the bearing are grease-lubricated ball bearings. Electropump have two mechanical seals independent of the direction of rotation on the pump side.
For sump drainage, open well, surface water collection sumps for flood water or water leakage in mine and drilling.
