S1F Non-Metallic 1″ (25mm) AODD – Ball Valve Pump

This legendary pump has proven the test of time as a trusted, class-leading air-operated double-diaphragm (AODD) pump for a variety of markets and applications.

The Sandpiper 1″ S1F Non-Metallic AODD Pump provides incredible lightweight portability with the versatility to handle both corrosive fluids and small suspended solids. It offers air-side interchangeability with Sandpiper’s S15, S20 and S30 pumps for reduced inventory costs.

The durable, bolted construction of the S1F is superior to the clamped-band construction pump, providing exceptional leak-free performance. This pump is designed to be driven by compressed air or nitrogen.




  1. 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).
  2. Trusted design: 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.
