It is designed for continuous operation, no pump house is required suction being at bottom, can draw water to the lowest level. Special anti corrosive process is carried out to wetted parts for longer life.

Impeller and rotor assembly are dynamically balanced for vibration free and noiseless operation.

Stationary part like discharge outlet, bye pass, bowl, suction case, housings etc are of graded C.I. casting and jackets and motor body, are hydraulically tested, shaft shall be S.S., Impeller shall be CI/Bronze/S.S. or any material required by client. Protecting sleeve be s.s., bearing bush shall be leaded tin bronze. Motor will have PVC. coated wire winding, thrust bearing will the graphite/S.S. plate duly ground and lapped.
