C.R.I. Centrifugal monoblock pump sets are powered by a totally enclosed fan cooled AC induction two pole motor. The motor stator is made of low 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 frame and usage of quality materials result in high performance and low-temperature rise thereby increasing the life cycle of the motor.
