• Maximum working pressure: 8.6 bar (125 psi)
• Compatible with a wide range of fluids, including those with solids up to 12.7 mm
• Stall-free low pulsation air valve for smooth and rapid changeover
• Four-bolt joint design for even sealing pressure and leak-free operation
• Modular, stall-resistant air valve design
• One-piece center section reduces leaks and maintenance
• Heavy-duty construction for long service life
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Expanded material offering for diverse applications

Applications:
Suitable for transferring fluids with solids in industries such as mining, agriculture, chemical processing, and general industrial applications. Handles abrasive, viscous, and shear-sensitive materials.

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
