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.
