The GRACO 654526 is a polypropylene (PP) air-operated double diaphragm pump designed for fluid transfer applications, including high viscosity materials. It features a center flange configuration and is intended for use in industrial environments requiring reliable, efficient, and low-maintenance fluid handling.

Key Features:

• Air-operated double diaphragm pump
• Husky 15120, 1-1/2 in (38.1 mm) ANSI porting
• Polypropylene (PP) center section, SP (Santoprene) seats, SP balls, SP diaphragm
• Up to 120 gpm (454 lpm)
• Fluid pressure up to 125 psi (8.6 bar, 0.86 MPa)
• Designed for use with a wide range of fluids, including high viscosity materials; not for use in European explosive atmospheres
• Stall-free low pulsation air valve for smooth and rapid changeover
• One-piece center section eliminates leaks and reduces maintenance
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Lube-free operation
• Compact, portable size
• Available in polypropylene and PVDF materials

Applications:
Industrial fluid transfer, handling of high viscosity materials, chemical processing, and other demanding environments where reliable, efficient, and low-maintenance pumps are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure correct alignment of center and end flanges during installation
• Follow manufacturer’s guidelines for air supply and fluid connections
• Regularly inspect diaphragms, seats, and balls for wear and replace as needed
• Use only recommended replacement parts for maintenance
