UNIQUE HEAVY-DUTY FLAP VALVE AODD PUMP
The flexible, portable and lightweight design of the SANDPIPER HDF1 heavy-duty flap valve pump offers maximum convenience when faced with the most common challenges in sump applications, mine dewatering and any liquid application involving solids.
The HDF1 has a superior flow rate to all other 1″ AODD pumps and is a proven and trusted solution even in the harshest applications, effortlessly moving abrasive slurries, suspended and non-suspended solids and line-size solids.
Small but Mighty Pump
The SANDPIPER pump design offers a small footprint, making it an excellent choice for both portable and permanent applications. The superior suction lift capabilities, combined with its solids-handling capabilities, make it the ideal solution for sump and dewatering applications.
The bottom discharge porting prevents settling solids from damaging the diaphragm and shortening the pump life. HDF1 pumps are thick wall-constructed of sand-casted aluminum, cast iron and stainless steel with elastomer and TPE (thermoplastic elastomer) diaphragms and check valves.
