S1F Non metallic

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.


  • 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).
  • 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.
