SB1 and SB25 Metallic 1" (25 mm) AODD – Ball Valve Pump


    The SANDPIPER 1" SB1 Heavy-Duty Ball Pump is an exclusive design to SANDPIPER and is best-in-class for moving thin-highly viscous and small, solids-laden fluids.

    The 1" metallic heavy-duty ball pump provides excellent suction lift capabilities and is designed to withstand the most rugged, harsh ball valve pumping applications. This flexible, durable pump offers a range of features including:

    • Compact design
    • Weighted check balls (30-60% heavier than solid rubber check balls, allowing for more consistent chamber filling)
    • Extended-wear packages
    • Ability to easily pump abrasives and slurries

    The SB1 also has a variety of porting options, which optimize performance and make installation easy:

    • Top-ported: For fluids containing floating solids, suspended solids or entrained gases. The discharge port is positioned above the center of the pump for easier evacuation and less build-up of solid material or gases.
    • Down-ported: For fluids containing settling solids. The discharge port is positioned below the center of the pump so solids settle in the elbow and are discharged. This helps reduce wear on the diaphragms and associated components.
    • Side-ported: For use in confined spaces. The ports are positioned with the center of the pump, allowing for installation in smaller, cramped spaces [available in 1" (25 mm) and 1½" (40 mm) sizes only].

    These porting configurations solve critical problems, such as solids and abrasives settling out of the liquid chamber into the ball check area, and are designed to outlast standard pumps.

    SB1 Pump Features Externally Serviceable Air Distribution System

    When dirty air enters an AODD pump, it will require frequent servicing of the air distribution system. SANDPIPER is the only AODD pump manufacturer to offer an externally serviceable air distribution system (ESADS+), which allows complete access to the main air and pilot valves without removing the pump from service. Repair or clean in five minutes (versus 55 minutes for competitors), reducing your downtime by as much as 90%.
