Applications:
Ideal for industrial fluid transfer, chemical processing, mining, wastewater treatment, and other applications requiring robust, high-flow, and reliable pumping solutions.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, and maintains warranty coverage.
• Ensure proper alignment of inlet and outlet connections to prevent leaks and reduce wear
• Use appropriate thread sealant for NPT connections
• Verify air supply pressure does not exceed recommended limits
• Regularly inspect diaphragms, seals, and air valve for wear and replace as needed
• Keep the air section clean and free from debris to maintain efficiency and longevity
• Perform routine inspections of diaphragms and seals
• Clean the pump and air section regularly
• Replace worn or damaged parts with genuine GRACO components
• Monitor for unusual noise or vibration, which may indicate maintenance needs
