Applications:
Industrial fluid transfer, including chemicals, paints, coatings, adhesives, and other abrasive or viscous materials. Suitable for mining, agriculture, manufacturing, and other heavy-duty environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump.
• 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 inlet/outlet port orientation and secure connections
• Regularly inspect and maintain diaphragms, seats, and balls for wear
