The GRACO 647630 is an air-operated double diaphragm pump with a remote aluminum center section, aluminum seats, Buna-N balls, and TPE diaphragm. It is designed for reliable, leak-free transfer of fluids such as water, antifreeze, and fuel in industrial applications.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050, 1" BSPT
• Remote aluminum center section, aluminum seats, Buna-N balls, TPE diaphragm
• Maximum free flow delivery: 50 gpm (189 lpm)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa)
• Industrial fluids such as water, antifreeze, and fuel
• Stall-free low pulsation air valve for smooth and rapid changeover
• One-piece center section eliminates leaks and reduces maintenance
• Bolted joint design for even sealing pressure and leak-free operation
• Externally serviceable spring-loaded pilot valves for faster changeover and reduced pulsation
• Longer diaphragm life (up to 5x longer than competitors)
• Modular air valve for installation flexibility
• Optional DataTrak™ for runaway protection and material usage tracking
• Optional pulse output for cycle count capability

Applications:
Industrial fluid transfer, including water, antifreeze, and fuel; suitable for environments requiring reliable, low-maintenance, and leak-free operation.
