Applications:
Used for evacuating and transferring fluids in industrial settings, including lubrication systems, chemical processing, and process fluid handling. Suitable for mining, agriculture, and manufacturing applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
• Follow all safety instructions and warnings in the manual
• Ensure proper torque (80 to 100 in-lb, 9.0 to 13.6 N-m) on critical fasteners
• Apply grease to lapped surfaces and bores as specified during assembly
• Leave center housing and air covers assembled during service unless otherwise required
• Consult the manual for specific installation and maintenance procedures
• Regularly inspect diaphragms, seats, and balls for wear
• Use only recommended lubricants and replacement parts
• Monitor for leaks and unusual noise
• Follow GRACO’s recommended service intervals
