All Products >> Agriculture & Residential Pumps >>Jet Self Priming Pumpsets – CJS Series

    C.R.I. Jet self priming pumpsets pump casing and ejector unit are designed carefully to give

    the best possible hydraulic efficiency and suction lift characteristics. These pumpsets 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.
