Applications:
Ideal for industrial fluid transfer, including chemical processing, mining, agriculture, and other sectors requiring high flow rates and reliable, low-maintenance pumping solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and warranty compliance.
• 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
• Install a shutoff valve in the fluid outlet line
• Follow torque instructions when installing or rotating manifolds
• Regularly inspect diaphragms, seats, and balls for wear
• Ensure proper grounding of the system
• Use only recommended replacement parts for maintenance
