Sandpiper S1F Metallic – 1” Air Operated Double Diaphragm Pump
The Sandpiper S1F 1″ Air Operated Double Diaphragm Pump has stood the test of time as a category leader, proving reliable for a variety of markets and applications. It’s a portable and versatile air operated pump, designed to handle both abrasive fluids and suspended solids.
The Sandpiper S1F 1″ Air Operated Double Diaphragm Pump offers air-side interchangeability with Sandpiper’s S15, S20, and S30 pumps to reduce inventory costs and facilitate spare parts management. This pump is designed to be operated by compressed air or nitrogen. If your pump needs to be operated by natural gas, take a look at Sandpiper’s G1F pump.
The robust bolted construction of the S1F is superior to that of clamped pumps, ensuring exceptional leak-free performance. Selectable materials for the pump body include aluminum, cast iron, and stainless steel with options for TPE (thermoplastic elastomers) and PTFE for diaphragms and check valves.
Features of the Sandpiper S1F 1″ Air Operated Double Diaphragm Pump:
- Maintenance: The Air Distribution System (ADS) is one of the most frequently replaced parts on pneumatic pumps. Only SANDPIPER’s ESADS+ feature allows full access to the ADS without removing the pump from service. Repair or cleaning in five minutes (compared to 55 minutes for competitors).
- Simplicity: SANDPIPER’s original ADS system is fully interchangeable, repairable, and serviceable online. Other manufacturers frequently change ADS designs, creating issues with interchangeability, obsolete inventory, and increased cost of ownership.
