• Maximum free flow delivery: 50 gpm (189 lpm)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) (Note: Some sources list 100 psi/7 bar; confirm with specific model documentation)
• Industrial fluids compatible with stainless steel, PTFE, and polypropylene wetted parts
• UL listed (for some models in the series)
• Stall-free low pulsation air valve for smooth and rapid changeover
• Reliable, robust construction for industrial use
• Ease of maintenance and serviceability
• Handles solids up to 1/8 in (3.2 mm)
• Maximum pump speed: 280 cycles per minute
• Displacement per cycle: 0.17 gal (0.64 liters)
• Maximum suction lift: 16 ft (4.9 m) dry, 29 ft (8.8 m) wet

Applications:
Industrial fluid transfer, including abrasive, viscous, or corrosive liquids; suitable for mining, agriculture, chemical processing, and general industrial use.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure all wetted parts are compatible with the fluid being pumped
• Connect air supply to the correct inlet size (1/2 in NPT female)
• Follow manufacturer’s instructions for mounting and piping
• Regularly inspect diaphragms and valves for wear and replace as needed
• Use appropriate thread sealant on all connections
• Periodically check for leaks and tighten connections
• Inspect diaphragms and balls for wear or damage
• Lubricate moving parts as recommended
• Keep air supply clean and dry to prevent contamination
