• Maximum 42 gpm (159 lpm)
• Maximum fluid pressure: 100 psi (7 bar, 700 kPa)
• Suitable for a wide range of industrial fluids, including those with solids up to 0.125 in (3.175 mm)
• UL listed
• Stall-free, low pulsation air valve for smooth operation
• Easy maintenance and repair
• Reliable, robust construction for demanding environments
• Suitable for continuous duty cycles

Applications:
Ideal for transferring fluids in industrial, mining, agricultural, and maintenance settings. Suitable for handling fluids with small solids, such as lubricants, coolants, and process chemicals.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment of pump and piping
• Use recommended fittings and seals for compatibility with fluid and environment
• Follow manufacturer guidelines for air supply and pressure settings
• Regularly inspect diaphragms and seals for wear and replace as needed
• Periodically check for leaks and unusual noises
• Lubricate moving parts as specified in the manual
• Replace diaphragms and seals at recommended intervals
• Store pump in a dry, clean environment when not in use
