Applications:
Ideal for transferring a wide range of fluids, including corrosive, abrasive, or viscous liquids, in industries such as mining, agriculture, manufacturing, and chemical processing. Suitable for applications requiring leak-free, reliable, and low-maintenance fluid handling.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment. Non-genuine parts may compromise safety and efficiency.
• Ensure proper alignment of pump components during assembly
• Use recommended air pressure settings (30–100 psi)
• Check for correct porting (center or end) as required by application
• Inspect diaphragms and balls for wear before installation
• Follow manufacturer guidelines for maintenance intervals
