• Maximum working pressure: 8.6 bar (125 psi) for aluminum/stainless steel with aluminum center section
• Compatible with a wide range of fluids, including high-viscosity and solids-containing materials
• Stall-free low pulsation air valve for smooth, rapid changeover
• Four-bolt joint design for even sealing and leak-free operation
• Three-piece manifold for installation flexibility
• Heavy-duty construction for long service life
• Modular, easy-to-maintain design
• Up to 5 times longer diaphragm life compared to previous models
• Improved efficiency (up to 40% more efficient)

Applications:
Ideal for fluid transfer in industrial, mining, agricultural, and manufacturing environments. Suitable for handling abrasive, viscous, or solids-laden fluids.

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 manufacturer torque instructions for manifold assembly
• Regularly inspect and maintain diaphragms, balls, and seals for wear
