Applications:
Industrial fluid transfer, fuel dispensing, oil and waste oil handling, chemical processing, and other applications requiring robust, chemically resistant pumps.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
• 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 pressure settings
• Regularly inspect diaphragms, seals, and valves for wear and replace as needed
• Maintain clean air supply to prevent contamination and ensure smooth operation
