Applications:
Industrial fluid transfer, including asphalt sealer, antifreeze, detergents, motor oil, hydraulic fluid, cutting oil, water, and wastewater transfer

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
• Ensure proper alignment and secure mounting to prevent vibration and leaks
• Use appropriate thread sealant on NPT connections
• Check air supply pressure (operating range: 20 to 120 psi)
• Inspect diaphragms and ball checks regularly for wear and replace as needed
• Follow manufacturer’s guidelines for maintenance intervals
