Applications:
Ideal for transferring chemicals, slurries, and abrasive fluids in industries such as mining, agriculture, manufacturing, and wastewater treatment. Suitable for handling fluids with solids up to 12.7 mm in size.

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 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 assembly and ensure proper grounding of the system
• Regularly inspect and maintain diaphragms, seats, and balls for wear
