C.R.I.’s vertical open well submersible pumps are ideally suitable for open wells where there is a wide fluctuation in water level.This works under water and it rest at the bottom of the well.Pump portion is of single stage (horizontal pump) & single or multi stage (Vertical pump) and fitted with cast iron casing and impeller. Pump volute chamber is designed to give the best possible hydraulic efficiency. Dynamically balanced impeller offer vibration free operation with long life.Prime mover is eco friendly wet wound type water filled rewindable. The stator windings are of water proof synthetic film insulated copper winding wires. It features water lubricated thrust and journal bearing. Motor is pre filled with clear, cold, pure, fresh filtered water.

Dynamically balanced rotor maintain uniform clearance thereby giving better efficiency and increase the life cycle of the water lubricated bush bearings. Specially designed high performance thrust bearings are used that can withstand high axial thrust loads and up thrust loads with wear and tear.Pressure equalizing rubber diaphragm is provided to guard against pressure and volume variations due to thermal expansion of water inside the motor. Motor sealing are made by means of ‘O’ rings, shaft seals and sand guard to prevent ingress of well water, sand and fibre particles in to the motor.
