GRACO Husky 1050E Series 1” (DN25) Electric Operated Double Diaphragm Pump

The only electric diaphragm pump on the market that will stall under pressure.  Up to 5 x more efficient than air operated diaphragm pumps.  Reduce pulsation without the addition of pulsation dampeners.  Self priming – can run dry.

FEATURES:

  • Eliminate unnecessary pump failures for your application.
  • Improve your facilities energy efficiency and create a quieter work environment for your employee.
  • Patent pending technology allows pump to stall under pressure preventing pump failures from clogged lines or closed valves.
  • Energy efficient  electric drive reduces energy consumption up to 5x compared to traditional air operated diaphragm pumps.
  • Seal-less diaphragm pump design eliminates leaking  rotational seals and failures due to run-dry pump conditions.
  • Ideal for applications that require low pulsation and a smooth flow.
  • The air charged drive allows the elimination or reduction of pulsation  WITHOUT expensive pulsation dampeners or surge tanks.
