Applications:
Industrial fluid transfer in mining, agriculture, manufacturing, and chemical processing. Suitable for handling corrosive, abrasive, or viscous 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.
• Install the pump as close as possible to the material source to minimize suction requirements and maximize performance
• Use grounded, flexible fluid hoses to reduce static sparking risk
• Install a fluid drain valve near the fluid outlet and a shutoff valve in the fluid outlet line
• Follow torque instructions for manifold installation and ensure proper grounding of the system
• Regularly inspect diaphragms, balls, and seats for wear and replace as needed
