Applications:
Suitable for a wide range of industrial fluid transfer applications, including chemical processing, mining, agriculture, and manufacturing. Handles abrasive, viscous, and corrosive fluids.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Install the pump as close as possible to the material source to maximize performance
• Minimize suction requirements for best results
• 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 for manifold installation
• Rotate center manifold(s) to change inlet/outlet port orientation as needed
• Regularly inspect diaphragms, balls, and seats for wear
• Ensure proper grounding to prevent static sparking
• Use only recommended replacement parts for maintenance
