Applications:
Industrial fluid transfer, including chemicals, oils, water, and wastewater treatment; suitable for mining, agriculture, and manufacturing environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure proper alignment of inlet and outlet connections
• Use appropriate thread sealant for NPT connections
• Check for leaks after installation
• Follow recommended air pressure settings (operates on as little as 20 psi, max 100 psi)
• Regularly inspect diaphragms and seals for wear
• Periodically check and replace diaphragms and seals as needed
• Clean pump internals to prevent clogging from solids
• Lubricate moving parts according to manufacturer guidelines
• Monitor for unusual noise or vibration
