Built for demanding sump applications, mine dewatering, wastewater handling, and industrial liquid transfer, this air operated double diaphragm pump provides dependable performance in harsh environments involving heavy solids and abrasive fluids.\u003c\/p\u003e\n\u003cp\u003eThe HDF4 uses a heavy-duty flap valve design that provides a large internal flow area, allowing solids up to nearly 3\" (75 mm) to pass through the pump. Its bottom discharge porting helps prevent settling solids from remaining inside the pumping chamber, reducing premature wear and improving pump life in slurry and solids-heavy applications.\u003c\/p\u003e\n\u003cp\u003eConstructed with thick wall sand-casted metallic materials, including aluminum, cast iron, and stainless steel options, the HDF4 is engineered for long-term durability. The pump also features a no-lube, no-stall air distribution valve and delivers a maximum flow rate of up to 310 GPM (1173 LPM), depending on material configuration.\u003c\/p\u003e\n\u003ch3 style=\"color: #263879;
