Description
HDF3 AND HDF4 3" (80MM) AND (100 MM) AODD - HEAVY DUTY FLAP VALVE PUMPS
The SANDPIPER HDF3 AND HDF4 METALLIC 3" (80 MM) AND 4" (100 MM) HEAVY DUTY FLAP VALVE PUMPS are designed for pumping fluids with line-size solids up to 3” and 4” respectively, making them ideal for sump applications, mine dewatering, and other demanding environments involving solids and abrasives. With an efficient flap valve system, these pumps minimize blockages and optimize suction lift, making them particularly suited for abrasive slurries and applications with high solids content.
HDF3 AND HDF4 AODD PUMP Key Features
- Superior Solids handling: Flap valves allow large line-sized solids (3” fo HDF3 and 4” for HDF4) to follow smoothly, reducing clogging and wear on the pump.
- Bottom Discharge porting: Prevents solids from settling in the pump chamber, extending diaphragm life and improving operational efficiency.
- Optimized Suction Lift: Capable of superior suction lift up to 24 ft, providing up to 15% greater lift than standard ball valve pumps, which is crucial for high-lift applications.
Application
- Sump Applications: efficiently handles large solids with minimal wear
- Mine Dewatering: Superior suction lift and durability for demanding mining environments
- Heavy-Duty Industrial Applications: ideal for handling abrasive and solids-laden fluids in extreme conditions.
Why Choose SANDPIPER AIR OPERATED DOUBLE DIAPHRAGM
- Reduced downtime: The flap valve system prevents clogging and enables smooth passage of solids, minimizing interruptions
- High-efficiency operation: Optimized for superior flow and suction lift, reducing maintenance and maximizing productivity.
- Versatile and Durable Construction: Built from sand-casted aluminum, cast iron, and stainless steel, these pumps withstand harsh environments with ease.
