• Maximum pump speed: 280 cpm
• Maximum suction lift: 16 ft (4.9 m) dry, 29 ft (8.8 m) wet

Applications:
Ideal for transferring chemicals, water, slurries, and other fluids in industrial, mining, and agricultural environments. Suitable for applications requiring chemical resistance and robust, reliable performance.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose (GRACO recommends Fluid Pressure Relief Kit, part number GR238428)
• Ensure proper alignment and secure mounting to minimize vibration and wear
• Regularly inspect diaphragms, balls, and seats for wear and replace as needed
• Follow manufacturer guidelines for air supply and fluid compatibility
• Perform routine inspections and maintenance as outlined in the manual
• Replace worn components with genuine GRACO parts
• Keep air supply clean and dry to prevent contamination and wear
• Monitor for leaks and unusual noises during operation
