CRI Borewell Submersible Pump (150 MM)




C.R.I. 150 mm (6") Borewell submersible pumpsets are built with different materials of construction together with extremely hardwearing bushes which makes this pumpsets highly durable. Radial flow submersible pumpsets are supplied with stainless Steel impellers and stage casings and mixed flow pumpsets are supplied with LTB-2 and casted steel impellers to give better performance and longer life. The optimal design of impellers and diffusers offers best possible  hydraulic efficiency. These pumpsets are powered by a water filled, rewindable submersible motor suitable for continuous duty. 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 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 efficiency and life cycle of the motor.
