The Graco Husky 716 D53311 is a 3/4" air-operated double-diaphragm (AODD) pump designed for industrial fluid-transfer applications. The Husky 716 uses compressed air to drive two diaphragms alternately, providing positive-displacement pumping without requiring an electric motor.
Its pneumatic design makes it suitable for applications where an air-powered pump is preferred, including chemical transfer, water and wastewater handling, coatings, process fluids and general industrial fluid transfer.
The pump is self-priming and can handle intermittent dry-running conditions when properly operated. The exact fluid compatibility depends on the diaphragm, seat, ball and wetted-material configuration.
Important: Verify the complete configuration of your pump before ordering, especially diaphragm/ball/seat materials and port configuration, as these affect chemical compatibility and application LineHuskyModel716Part NumberD53311Pump TypeAir-Operated Double DiaphragmAbbreviationAODDPort Size3/4"Drive TypeCompressed AirPump ActionDouble DiaphragmPump StylePositive DisplacementOperationPneumaticMotor Fluid TransferConditionNew, if applicableSuggested Item Specifics
