The SANDPIPER HP20 2" (50 mm) Metallic 2:1 High-Pressure Pump provides nearly double the force in applications where pressure is priority and 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.

Incorporating two additional air chambers and one extra air side driver diaphragm, doubles 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. SANDPIPER AODD pumps achieve high discharge pressures and excellent flow rates.
