The Husky 307 is a positive displacement, air-operated double diaphragm pump designed for reliable transfer of a wide range of fluids. It is constructed from polypropylene or acetal, with PTFE diaphragms and balls, and is intended for use in industrial and maintenance applications where robust, easy-to-service fluid transfer is required.

Key Features:

• Air Operated Double Diaphragm Pump (AODD)
• Husky 307, 3/8 in. NPT
• Polypropylene or acetal body, PTFE diaphragms and balls, acetal seats
• Up to 7 GPM (26.5 LPM)
• Operates on as little as 20 psi (1.4 bar, 0.14 MPa)
• Compatible with a wide range of fluids, including oils, chemicals, and water-based solutions
• Quick and easy assembly/disassembly
• Easy-to-service air valve and ball checks
• Stall-free low pulsation air valve for smooth operation
• Split manifold option for pumping multiple fluids without mixing
• Fully-groundable acetal model available
• Every pump is tested prior to shipping

Applications:
Industrial fluid transfer, maintenance, lubrication, chemical handling, and other applications requiring reliable, low-maintenance pumping solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose (use GR238899 for Husky 307)
• Ensure proper grounding for acetal models
• Follow manufacturer guidelines for air supply and fluid compatibility
• Regularly inspect and service air valve and ball checks for best performance
