C.R.I.'s R – Series motors are hermetically sealed encapsulated and water lubricated type with Removable cable lead out. The stator winding are of enamelled copper wire and the wounded stator in mounted in a stainless steel shell and completely protected by a stainless steel cylinder and stator room is pre-filled with Resin. Dynamically balanced rotor of these 'R' series motors maintain uniform clearance there bygiving 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. Mounting dimension of Motors are accordance with NEMA standard.

C.R.I.'s L – Series motors are developed with diligence complying with all safety standards and giving importance to the customers need. All the components that are in contact with water is made of AISI 304 Stainless Steel. The motor is prefilled with edible grade oil which acts as coolant as well as lubricant and heat dissipation media. Dynamically balanced rotor of these 'L' series motors are equipped with quality ball bearing maintain uniform clearance thereby giving better efficiency and increase the life cycle. The shaft extension is made of 300 series Stainless Steel to avoid splines worn out. High quality carbon / ceramic mechanic seal and oil seal made of Nitrile rubber and used to ensure better sealing system. For easy maintenance and safe handling plug in type removable cable leads are provided. Mounting dimension of Motors are accordance with NEMA standard.

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.
