The SH2-M pump is a 2:1 ratio, high-pressure, single-acting diaphragm pump powered via compressed air. As the only high-pressure, air-operated diaphragm flap valve pump in the world, the unit can deliver discharge pressures twice the inlet pressure up to 250 psig (17.2 barg).

The pump can be utilized in filter press feeds and other demanding applications requiring higher discharge pressures and/or solids handling that most air-operated single-diaphragm (AOD) pumps are not capable of achieving.

This pump is engineered with metallic seats and heavy-duty flap valves to help ensure a durable valve seal for performance in high-pressure applications. Unlike other high-pressure pumps on the market, the SANDPIPER SH2-M unit features a balanced diaphragm design. This design allows for a minimal pressure differential across the diaphragm, helping to decrease the need for replacement parts–this effectively decreases downtime and ultimately lowers the total cost of ownership.

The SH2-M high-pressure pump is available in both aluminum and cast iron with various diaphragm (elastomer) options.
