• Maximum flow rate: 100 GPM (378.5 LPM)
• Maximum fluid pressure: 120 psi (8.4 bar, 0.84 MPa)
• ATEX, CE (Note: Some models may not be approved for European explosive atmospheres; check specific documentation)
• Patented, high-reliability closed center air valve (online serviceable)
• Epoxy-coated air section for tough environments
• Lube-free operation
• Easy-to-service air valve and ball checks
• Compact, portable size for high flow applications

Applications:
Industrial fluid transfer, including chemical, mining, and agricultural applications. Suitable for handling abrasive, corrosive, or viscous fluids.

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 of inlet and outlet connections (1.5-inch NPT or BSP or ANSI-flange)
• Use appropriate thread sealant for leak-free installation
• Check air supply (1/2-inch NPT female inlet) and ensure it meets pump requirements (max 120 psi)
• Inspect diaphragms and seats before installation for damage
• Follow manufacturer’s torque specifications for all connections
• Regularly inspect diaphragms, balls, and seats for wear or damage
• Clean pump internals after use with aggressive or corrosive fluids
• Lubricate only if specified by manufacturer (typically lube-free operation)
• Replace worn parts with genuine GRACO components
