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