• Lube-free operation
• Compact, portable size
• Highest fluid flow rate in its class
• Overall improved air efficiency

Applications:
Transfer of chemicals, solvents, slurries, and other fluids in industrial, mining, agricultural, and manufacturing environments where chemical resistance and reliability are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses rated for the intended fluid and pressure
• Follow manufacturer guidelines for air supply and fluid connections
• Regularly inspect diaphragms, balls, and seats for wear and replace as needed
• Keep the pump and surrounding area clean to prevent contamination
