The EH2-M pump is a 2:1 ratio high-pressure pump powered via compressed air. Capable of delivering discharge pressures twice the inlet pressure up to 250 psig (17.2 barg), the EH2-M pump is designed for durability. The pump can be utilized in demanding applications, such as filter press feeds, as well as other critical applications requiring higher discharge pressures most air-operated diaphragm (AOD) pumps aren’t capable of achieving.

This pump is engineered to include weighted check balls and metallic seats to help ensure a robust and durable valve seal for performance in high-pressure applications. Unlike other high-pressure pumps on the market, the SANDPIPER EH2-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—effectively decreasing downtime and, ultimately, lowering the total cost of ownership.

The EH2-M high-pressure pump is available in cast iron and stainless steel with various diaphragm (elastomer) options.
