Husky 716 Transfer Pump

The Graco Husky 716 double diaphragm pump is engineered to reliably handle fluid transfer applications involving oil, water, antifreeze, and windshield washer fluid. Inside the pump are no mechanical seals which prevent leaks and failures. Runs under 85dBa with muffler capability to reduce noise even more. Air valve and ball checks are easy to service so repairs are fast. The Graco Husky 716 provides a maximum flow rate of 16 GPM.
