Applications:
Industrial fluid transfer, including handling of solids, slurries, and abrasive materials. Suitable for mining, chemical processing, water treatment, and other demanding environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and gaskets for NPT end port connections
• Verify electrical compatibility with 240V supply and proper grounding
• Follow manufacturer guidelines for initial priming and startup
• Regularly inspect diaphragms, balls, and seals for wear and replace as needed
• Perform routine inspections and maintenance as recommended by GRACO
• Replace worn or damaged components with genuine parts
• Keep the pump and surrounding area clean to prevent contamination
• Monitor for leaks and unusual noise during operation
