The GRACO D53311 Husky 716 AL is an air-operated double diaphragm pump constructed with an aluminum fluid section, stainless steel seat, PTFE ball, and PTFE diaphragm. It is designed for the safe and efficient transfer or evacuation of fluids in industrial environments, featuring robust construction and compatibility with a wide range of fluids.

Key Features:

• Air Operated Double Diaphragm Pump
• Husky 716 AL, 3/4" (19.05 mm) NPT
• Aluminum fluid section, stainless steel seat, PTFE ball, PTFE diaphragm, polypropylene standard air valve (NPT) center section
• 16 gpm (61 l/min)
• Maximum fluid discharge pressure: 100 psi (7 bar, 0.7 MPa); Maximum air input pressure: 100 psi (7 bar, 0.7 MPa)
• Compatible with a wide range of industrial fluids; maximum pumpable solids: 3/32 in (2.5 mm)
• ATEX rated (II 2 GD Ex h IIC 66°C...135°C Gb Ex h IIIC T135°C Db); see manual for specific T-code based on fluid temperature
• Center- and end-porting options
• No mechanical seals to leak or fail
• Runs quietly at less than 85 dBa with remote muffler capability
• Easy-to-service air valve and ball checks
• External controller for remote control capabilities

Applications:
Used for evacuating and transferring fluids in industrial settings, including manufacturing, mining, and agriculture. Suitable for handling fluids with small solids and requiring reliable, leak-free operation.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Read all instruction manuals, tags, and labels before operating the equipment.
• Use only for professional applications.
• Install an air line filter to remove dirt and moisture from the compressed air supply.
• Use a minimum 1/4 in. (6.3 mm) ID electrically conductive, flexible air hose between accessories and the pump air inlet.
• If using a conductive (acetal) pump, use conductive hoses; if using a non-conductive pump, ground the fluid system.
• At inlet fluid pressures greater than 15 psi (0.1 MPa, 1 bar), diaphragm life will be shortened.
