Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment. Non-genuine parts may compromise safety and efficiency.
• Ensure proper alignment of pump components during assembly
• Use recommended thread sealants for BSPT connections
• Check for leaks after installation and during initial operation
• Follow manufacturer’s torque specifications for bolted joints
• Regularly inspect and maintain diaphragms and seals to prevent downtime
