Applications:
Industrial fluid transfer, including antifreeze, detergents, motor oil, hydraulic fluid, water, and wastewater transfer in mining, agriculture, and other heavy-duty environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure all connections are tight and leak-free before operation
• Follow manufacturer guidelines for air supply and fluid compatibility
• Regularly inspect and maintain the air valve and diaphragm for optimal performance
• Use appropriate personal protective equipment during installation and maintenance
• Regularly check for leaks and wear
• Inspect and replace diaphragms as needed
• Keep air supply clean and dry
• Service the air valve externally without removing the pump from the system
