The Husky 1050HP air-operated diaphragm pump 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.

Benefits of the Husky 1050HP Double Diaphragm Pump

  • Increased fluid pressure without sacrificing flow
  • Low-high pressure mode valve lets you operate the pump as a standard AODD or a high pressure AODD
  • Reduce air consumption up to 50% with the low pressure mode
  • Same repair parts as the Husky 1050 diaphragm pump

Overview
Maximum fluid flow for High Pressure Mode
50 gpm (189 l/min)
Maximum Fluid Discharge Pressure
125 psi (17.2 bars, 1.72 MPa)
Maximum size pumpable solids
1/8 in (3.2 mm)
