For a top range of air-operated double-diaphragm (AODD) pumps, businesses rely on York Fluid Controls. The supplier offers a complete lineup of fluid-control solutions by Sandpiper, such as the HDF1 heavy-duty flap valve pump. This unit is recommended for abrasive slurries, as well as suspended, non-suspended, or line-size solids. Each of these valve pumps is configured with bottom discharge porting, which stops settling solids from reducing pump life while creating better suction lift.
The HDF1 comes in three variations that are thick-wall-constructed of stainless steel, sand-casted aluminum, or cast iron, while the diaphragms and check valves are made of elastomer and thermal plastic elastomer. The stainless steel pump has a shipping weight of 36 kg, while that of the aluminum pump equals 12 kg, and the cast iron one equals 34 kg.
This Sandpiper heavy-duty flap valve pump has a port size of one inch NPT and a capacity of up to 265 litres per minute. The air distribution valve has a no-lube, no-stall design, and the pump handles solids of up to 25.4 millimetres, with heads up to 125 pounds per square inch (psi), or 88 metres of water. The HDF1 also has a displacement/stroke of 38 per cent of a litre, as well as a maximum operating pressure of 125 psi.
An advantage of investing in this heavy-duty flap valve pump from York Fluid Controls is the wide variety of materials in its full construction, with various respective benefits. Its 316 stainless steel offers high corrosion resistance, while the alloy C meets industry specifications for nickel and nickel alloy. Aside from metals, the HDF1 contains conductive acetal, EPDM, fluorocarbon (FKM), hytrel, neoprene, nitrile, nylon, polypropylene, PVDF, santoprene, UHMW PE, urethane, and virgin PTFE.
