    Normal vertical discharge. Tapped openings for suction, discharge, drain plug, and gauge connections.

    The back-pull-out feature allows the motor, motor adapter, seal, and impeller to be removed without disturbing pipe connections. Maintenance is therefore considerably simplified.


    Enclosed type, all brass and fully balanced.

    Standard units furnished non-overloading for continuous duty.

    Pump Shaft

    Models 902B - 906B feature brass stub shaft, (416 stainless optional). Can be replaced easily.

    Models 907B - 910B feature 416 stainless steel stub shaft assuring the same out-standing protection against corrosion and pitting.


    Models 902B - 906B feature pressure stabilizing hydro-lock at no extra cost. The hydro-lock forms an efficient seal between the suction and discharge of the pump. Ideal for small centrifugal pumps.

    Shaft Seal

    Carbon/Ceramic faces, BUNA-N elastomer and stainless steel parts, suitable for water to 211°F intermittent duty, 180°F continuous duty. For higher temperatures, Viton elastomer option available - consult factory.
