Features and Benefits of the Heavy Duty Flap Valve Pumps


    SA1 heavy-duty flap valve AODD pumps are:

    • Recommended for abrasive slurries, suspended and non-suspended solids and line-size solids.
    • Are configured with bottom discharge porting to prevent settling solids from shortening pump life and provide superior suction lift.
    • Are thick-wall constructed of sand-casted aluminum, cast iron and stainless steel with elastomer and TPE (thermoplastic elastomer) diaphragms and check valves. See tabs below for a complete description.


    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%.
