Self Priming Pump NR & ENR Series

Self Priming Pump NR & ENR Series

C.R.I. Self Priming Pump NR & ENR Series are power-driven by a totally enclosed fan cooled AC induction two pole motor, suitable for continuous duty. The motor stator is made of low watt loss silicon laminations assembled under pressure and rigidly locked in the frame.

The windings are of high – grade enamelled copper wire and are varnish impregnated. Construction of motor frames and usage of quality materials result in high performance. And also noise-free operation and low-temperature rise thereby increasing the life cycle of the motor. Pumps volute chamber and impellers are designed to give the best possible hydraulic efficiency and suction lift characteristics in Self Priming Pump NR & ENR Series.
