Air-powered diaphragm pump delivers discharge pressure, up to 250 psi maximum, equal to twice the inlet air pressure (2:1 ratio). The pump is designed for filter press feed or similar applications where higher discharge pressures are required. Some types are available with flap check valves for greater solids-handling capability. See Model SH2-M Data Sheet for specifics.

The GRACO Husky™ 1050HP is the first pump on the market that allows users to choose between low pressure and high pressure operating modes with Graco's low-high pressure mode valve. High pressure operation isn't always required, so switch to the low pressure mode to reduce air consumption up to 50%. These features, combined with the quality and reliability of our standard Husky™ diaphragm pump design; make this one of the most unique high pressure diaphragm pumps on the market.
