HP20 Metallic AODD Pump (High Pressure Pump) is a 2:1 high-pressure diaphragm pump that provides nearly double the force in applications where pressure is a priority and with an excellent flow rates are a must. This high-pressure air pump is ideal for thick, viscous fluids (high specific gravity), high head pressure applications, and moving fluids a long distance.
This series of air-operated double diaphragm pump incorporates two additional air chambers and one extra side driver diaphragm, double the surface area on which air pressure is exerted. This magnifies the force by nearly doubling the air inlet pressure. The magnified pressure is delivered directly to the pumped fluid via the fluid diaphragms. The Sandpiper HP20 Metallic AODD Pump achieve high discharge pressures and excellent flow rates.
