These motors are hermetically sealed, encapsulated and water lubricated type with 2/3 wire replaceable leads. The stator windings  are of enameled copper wires. The resin filled in the space between the stator and the stainless-steel cylinder dissipates heat quickly, resulting in longer motor life. The stator shell of these motors is made of high-grade 304/316 stainless-steel and housings are provided with Stainless-steel shells. All the rotating parts of these motors are dynamically balanced to maintain uniform clearance, better efficiency and better life cycle. Specially designed high performance thrust bearings are used to withstand high axial and upthrust loads with minimum wear & tear. Pressure equalizing rubber diaphragm is provided to, maintain the internal pressure of the water inside. 'O' rings, shaft seals and sand guard are used to avoid ingress of well ater, sand and fiber particles into the motor. Except stator other portions of the motor are prefilled with deionised water containing propylene glycol (anti-freeze agent), which serves as coolant & lubricant for rotor, bushes and thrust bearing. It is mandatory to install C.R.I. Control Boxes for all Single Phase 3-wire motors.
