AODD Pumps

Standard Duty Pumps

This legendary Standard Duty 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.

This pump is designed to be driven by compressed air or nitrogen. The durable, bolted construction 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.

Features & Benefits

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.
