The Sandpiper® ¼"" (6 mm) air-operated double-diaphragm (AODD) pump is engineered with original equipment manufacturers (OEMs) in mind and provides tremendous system flexibility.

The PB ¼"" is one of the quietest and most flexible AODD pumps in the compact class. Featuring a patented air valve system, this AODD pump provides non-stalling, non-icing, lube-free operation for years of dependable service.

The suction and discharge manifolds have multiple porting options. Available in polypropylene, conductive acetal and PVDF (Kynar) materials of construction, this small, yet powerful pump is ideally suited for dispensing inks, coatings, paints, adhesives, oils and other chemicals.
