Centrifugal Regenerative Pump sets PE/PS/NR ENR & Shine Series

C.R.I. Centrifugal Regenerative pump sets are power-driven by a totally enclosed fan cooled

AC induction two pole motor, suitable for continuous duty. Motor stator is made of low watt

loss silicon steel laminations assembled under pressure and rigidly locked in the frame.

The windings are of high – grade enameled copper wire and are varnish impregnated.

Construction of motor frames and usage of quality materials result in high performance,

noise free operation and low temperature rise thereby increasing the life cycle of the motor.

Non -self priming model is with end suction and radial delivery.
