Deepwell Submersible Motors
W-Series Water Filled Rewindable

W-SERIES-Water-Filled-Rewindable-Motors

C.R.I. Sumersible Motors are eco-friendly wet type, waterfilled rewindable. The stator windings are of water proof synthetic film insulated copper winding wires. It features water lubricated thrust and journal bearings. Motor is pre-filled with clear, cold, pure, fresh, filtered water. However, on request motors can be pre-filled with water and propylene glycol (Anti-freeze agent) for places where the temperature is below the freezing conditions. Dynamically balanced rotors of these 'W' series motors maintain uniform clearance there by 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 axial thrust loads and upthrust loads with minimum wear and tear. Pressure equalizing rubber diaphragm is provided to guard the pressure and volume variations of the water inside the motor. Motor sealing are made by means of 'O' rings, shaft seals and sand guard to avoid ingress of well water, sand and fiber particle into the motor.Mounting dimensions are in accordance with the NEMA mounting standard.
