Sandpiper
Air Operated Diaphragm Pumps

The Sandpiper range of air operate diaphragm pumps are manufactured in the USA and are available in aluminum, cast iron, stainless steel, Hastelloy equivalent, Polypropylene and conductive Polypropylene, PVDF and conductive PVDF, nylon and conductive acetal.

Self-priming and sealess, Sandpiper diaphragm pumps are ideal for abrasive, semi-solid, corrosive and shear sensitive materials. They are also chosen for applications where electricity is not available, or cannot be used due to safety conditions. Diaphragm pumps provide pollution-free and energy-efficient operation, with fewer moving parts than conventional motor-driven pumps.

Principal markets served by Sandpiper diaphragm pumps include mining, chemicals, paints, food processing, electronics, construction, industrial maintenance, utilities, process industries and wastewater processing.

HDF Pumps are recommended for abrasive slurries, suspended and non-suspended solids and line-size solids. All SANDPIPER® Heavy Duty Flap Pumps are configured with bottom discharge porting to prevent settling solids from shortening pump life and provide superior suction lift. HDF3-M/HDF4-M pumps are thick wall constructed of Cast Iron with elastomer and TPE (thermal plastic elastomer) diaphragms and check valves

lap valve pumps are especially recommended for slurries and liquids with suspended solids.
Flap valve pumps are especially recommended for slurries and liquids with suspended solids. Flap valves allow passage of line-size solids without damage of solid or pump shafts. Performance Criteria:
