|
C.R.I. 100 mm (4’) Borewell submersible pumpsets are built with impellers & diffusers made of thermo plastics and other vital components like check valve housing and suction inter connector which are made of graded cast iron, outer shell made of high quality stainless steel. The optimal design of impellers and diffusers offers best possible hydraulic efficiency. These pumps are powered by a water filled, rewindable submersible motor suitable for continuous duty. The stator is wound with special waterproof 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. Specially designed high performance thrust bearings (SS with Carbon) are used to withstand axial and down thrust loads with minimum wear and tear. Dynamically balanced rotor gives vibration free and noise free operation, thereby increases both efficiency and life cycle of the motor.
