C.R.I. "SM Series" Self-priming Non-Clog Monoblock Pump's volute chamber and impellers are designed to give the best possible hydraulic efficiency and suction lift characteristics. These pumps are powered by a totally enclosed fan cooled A.C. Induction motor. Motor stator is made of low watt loss silicon steel laminations assembled under pressure and rigidly locked in the frame. Construction of motor frames and usage of quality materials result in high performance and low temperature rise thereby increasing the life cycle of the motor.
