Husky 1050HP High Pressure Air-Operated Diaphragm Pump

1 inch Air-Operated Triple Diaphragm Pump

The Husky 1050HP has a 1 inch (25.4mm) connection and is available in aluminum and stainless steel. Choose between low pressure and high pressure operating modes with Graco’s low-high pressure mode valve.

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.

Description

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
