Rewindable motors are built for dependable operation in larger water wells. Water lubricated radial and thrust bearings for maintenance-free operation are fitted in a rewindable submersible motor.A special diaphragm ensures pressure compensation inside the motor.The rewindable submersible motor is filled with motor liquid ensuring sufficient lubrication of radial bearings.
CRI Fluids rewindable submersible motor technology reduces the risk of hot spots in the motor as the liquid inside has a uniform contact with active parts.
6″ Water Filled Rewindable Submersible Motors
C.R.I. "W series" motors are deep well / bore hole rewindable submersible type, pre-filled with water, which acts as coolant and lubricant. These motors are available in three phase power supply and suitable for both normal & high temperature applications. Rotors are supported with bush and thrust bearings to withstand maximum axial and radial thrust loads. All mounting dimensions are in accordance with NEMA standards.
