C.R.I. 250 mm (10") Borewell Submersible pumpset is made with different materials of construction together with extremely tough hardwearing bushes which make this pumset highly durable. This pumpset is supplied with stainless steel & LTB-2 impellers to give better performance and longer life. The optimal design of impellers and diffusers offers best possible hydraulic efficiency. This pumpset is powered by a water filled, rewindable submersible motor, which is suitable for continuous duty. The stator is wound with special waterproof synthetic film insulated copper winding wires and made up of low watt loss silicon steel laminations assembled under pressure and rigidly locked in stainless steel stator shell. Specially designed thrust bearings (SS AISI – 420 with graphite 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 efficiency and life cycle of the motor.
