S1F Metallic 1" (25 mm) AODD – Ball Valve Pump


    This legendary 1" pump has stood the test of time as a class-leading, trusted air-operated double-diaphragm (AODD) pump for a variety of markets and applications. It provides portability and versatility. It is equipped to handle abrasive fluids and suspended solids.

    The SANDPIPER 1" S1F Metallic AODD Pump offers air-side interchangeability with SANDPIPER’s S15, S20 and S30 pumps for reduced inventory costs. This pump is designed to be driven by compressed air or nitrogen. If your pump needs to be driven by natural gas, check out the SANDPIPER G1F pump.

    The durable, bolted construction of the S1F is superior to the clamped-band construction pump, providing exceptional leak-free performance. Material of construction options include: aluminum, cast iron and stainless steel with elastomer TPE (thermoplastic elastomers) and PTFE options in diaphragms and check valves.

    S1F Features

    Serviceability: The air distribution system (ADS) is one of the most frequently serviced parts of any AODD pump. Only SANDPIPER's ESADS+ feature allows access to the complete ADS without removing the pump from service. Repair or clean in five minutes (versus 55 minutes for competitors).

    Simplicity: SANDPIPER’S original ADS is fully interchangeable, repairable and inline-serviceable. Other manufacturers frequently change ADS designs, creating issues with interchangeability, obsolete inventory and increased cost of ownership.
