HDB1½ and HDB40 Metallic 1½" (40 mm) AODD – Ball Valve Pump

    SANDPIPER Side-Ported and Compact Air-Operated Double-Diaphragm Pump

    SANDPIPER’s exclusive 1½" heavy-duty ball pump provides excellent suction lift capabilities and is designed to withstand the most rugged and harsh ball valve pumping applications. The compact 1½" metallic pump has thick-walled construction and is part of our Evolution portfolio improvement. This means this pump has been optimized for the maximum amount of flow capacity with the least amount of air/gas consumption.

    The 1½" heavy-duty ball pump is available with a side-ported option, which makes installation easy, optimizes performance on the pumped fluid and solves critical pumping problems.

    SANDPIPER Heavy-Duty Ball Valve Pump Features

    These pumps are enhanced with extended-wear packages and are your optimal solution for abrasive-slurry applications. Features include:

    • Side-ported option: For use in confined spaces. Ports are positioned with the center of the pump, allowing for installation in smaller, confined spaces.

    HDB Down Ported Advantage

    • Heavy-duty plunger bushings and actuator pins: Designed to withstand severe applications
    • Diaphragm wear pads: Installed between the diaphragm and outer diaphragm plate, providing a secondary wear surface that extends the life of the diaphragm
    • Thicker, more robust wetted castings: Provide extended wear resistance
    • Heavy-duty weighted check valve balls: Are 30-60% heavier than solid rubber check balls, allowing for more consistent chamber filling
