C.R.I. Jet self priming pump sets pump casing and ejector unit are designed carefully to give
the best possible hydraulic efficiency and suction lift characteristics. These pump sets are
powered by a totally enclosed fan cooled AC induction motor, suitable for continuous duty.
Motor stator is made of low watt loss steel laminations assembled under pressure and
rigidly locked in the frame. The varnish impregnated windings made of enameled copper
wire offer excellent resistance.
