C.R.I. Open well Submersible pump sets are ideally suitable for open wells or tanks where a

wide fluctuation of water level occur. This work under water and rest at the bottom of the well.

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 silicon steel laminations assembled under pressure and rigidly locked.

Motor sealing is made by polymers, rings, oil seals and sand guard to avoid ingress of

well water / sand into the motor. Pressure equalizing rubber diaphragm is provided to guard

the pressure and volume variation of water inside motor. Motor must be filled with clear,

cold, drinking water as detailed in our operators manual. Three -phase motor requires an

adequate motor protection control panel.
