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

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.
