Applications:
Ideal for transferring chemicals, slurries, viscous fluids, and other industrial liquids in mining, agriculture, manufacturing, and processing industries.

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 minimize suction requirements and maximize performance
• Use grounded, flexible fluid hoses to reduce the risk of static sparking
• Install a fluid drain valve near the fluid outlet and a shutoff valve in the fluid outlet line
• Follow torque instructions for manifold assembly to ensure leak-free operation
• Regularly inspect and maintain diaphragms, seats, and balls for wear and replace as needed
