C.R.I. 175 mm (7") borewell sumbersible pumpset is made up with rigid materials of construction together with extremely tough hardwearing bushes which make this pumpset highly durable. This pumpset is supplied with stainless steel & LTB-2 impellers to give better performance and longer life and other vital components like check valve housing, stage bowls and suction inter connector, are all made of graded cast iron. The optimal design of impellers and diffusers offers best possible hydraulic efficiency. This pumpset is powered by a water filled, rewindable sumbersible 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 sillicon steel laminations assembled under pressure and rigidly locked in stainless steel stator shell. Specially desinged 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 operations, thereby increases efficiency and life cycle of the motor. This 175mm submersible pumpsets are supplied with 150mm (6") motor combination only.
