ROBUST AODD PUMP FOR CHEMICAL TRANSFER APPLICATIONS

The SANDPIPER S20 non-metallic air-operated double-diaphragm (AODD) pump’s time-tested, rugged design exclusively features three-piece bolted manifolds that enable reorientation of the porting connections to suit the unique needs of your process.

This pump is ideal for chemical transfer, bulk transfer and a wide variety of process applications.

S20 Key Features

Available in corrosion-resistant polypropylene or PVDF
Available with SANDPIPER’s one-piece Synthesis™ PTFE diaphragm
ESADS+ air distribution system: the only pump in its class with an externally serviceable air distribution system (see below)
Bolted construction with stainless steel fasteners

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.
