• Aluminum center section and seats, polychloroprene (CR) standard balls and diaphragm
• Up to 300 gpm (1,135 lpm)
• Maximum air pressure: 125 psi (0.86 MPa, 8.6 bar)
• Four-bolt joint design for even sealing and leak-free operation
• Three-piece manifold for installation flexibility
• Modular stall-resistant air valve design
• One-piece center section reduces leaks and maintenance
• Up to 40% more efficient than comparable pumps
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Heavy-duty construction for reliability and long service life

Applications:
Ideal for transferring fluids in industrial, mining, agricultural, and manufacturing environments. Suitable for handling a variety of liquids, including those with abrasive or corrosive properties.

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 to enhance pump efficiency
• 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 assembly
