All Products >> Agriculture & Residential Pumps >>Centrifugal Monoblock Pumps – ACM Series

 

  • C.R.I. Centrifugal Monoblock pumpsets 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.
