Applications:
Industrial fluid transfer, fuel dispensing, water and antifreeze transfer, lubrication systems, and other applications requiring reliable, efficient pumping of compatible fluids

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Ensure proper alignment of inlet and outlet connections (1" BSPT for this model)
• Use appropriate thread sealant for leak-free installation
• Check air supply (1/2" NPT air inlet) and ensure it meets pump requirements
• Follow GRACO’s recommended maintenance schedule for diaphragm and seat inspection/replacement
• Install a pressure relief valve if required for specific applications (e.g., fuel dispensing)
• Regularly inspect diaphragms, seats, and balls for wear
• Keep pump and surrounding area clean to prevent contamination
• Use only compatible fluids as specified by GRACO
• Consult the equipment manual for detailed installation and maintenance procedures
