The Sandpiper 2″ heavy-duty flap valve pump has a proven design that solves the most common challenges in sump applications, mine dewatering and any liquid application involving solids.
This metallic air-operated double-diaphragm (AODD) pump is recommended for abrasive slurries, suspended and non-suspended solids and line-size solids. It is configured with bottom discharge porting to prevent settling solids from shortening pump life and provide superior suction lift.
HDF2 pumps are thick-wall constructed of sand-casted aluminum, cast iron and stainless steel with elastomer and TPE (thermoplastic elastomer) diaphragms and check valves.
