These pumpsets are powered by a totally enclosed fan cooled AC induction two pole motor suitable for continuous duty with main dimensions complying with IEC standards. 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 frames and usage of quality materials results in high performance and low temperature rise thereby increasing the life cycle of the pumps.
