C.R.I. Centrifugal jet self priming pump casing and ejector unit are designed carefully to give the best possible hydraulic efficiency and good suction lift characteristics. These pumpsets are powered by a TEFC AC induction motor, suitable for continuous duty. Motor stator is made of low watt loss ferro silicon steel laminations assembled under pressure and rigidly locked in the frame. The varnish impregnated windings made of enameled copper wire offer excellent resistance. Construction of motor frame and usage of quality materials result in high performance and low temperature raise, thereby increasing the life cycle of the motor.
