Vertical Openwell Submersible Pumps - CVS Series

These centrifugal pumps are ideally suitable for openwells or tanks where there is a wide fluctuation in water level. This works under water and it rests at bottom of the well. Hence suction and priming problem do not arise. Pump's volute chamber is designed to give the best possible hydraulic efficiency. Dynamically balanced impeller offers vibration free operation with long life. Prime mover is rewindable, water - cooled motor. Specially designed water lubricated bearings are used to withstand axial thrust loads with minimum wear and tear. The stator is wound with special water proof synthetic film insulated copper winding wires and made up of low watt loss steel laminations assembled under pressure and rigidly locked in stainless steel stator shell.
