7″ Submersible Pump


Bore well Submersible Pump sets are powered by water filled, rewindable submersible which is made for continuous duty. The stator is wound with special water proof synthetic film insulated copper winding wires and made up of watt loss silicon steel laminations assembled under pressure and rigidly locked in stainless steel stator shell. T-Bolt & Thread type design in all motor ensures rigid construction. Open design of Impellers and diffusers offers best possible high efficiency in low voltage. Built-in check valve and pressure back flow and reduces the risk of water hammering.
