The GRACO 647035 is an air-operated double diaphragm pump designed for transferring fluids in industrial applications. It features a standard aluminum center section, Santoprene™ (SP) seats, balls, and diaphragm, providing chemical resistance and durability. This pump is intended for use in demanding environments where reliable fluid transfer is required.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 1050 AL, 1 in. (25.4 mm) NPT
• Aluminum center section and housing; Santoprene™ (SP) seats, balls, and diaphragm
• 50 gpm (189 lpm) maximum free flow delivery
• 125 psi (8.6 bar, 0.86 MPa) maximum fluid working pressure
• Designed for use with a wide range of industrial fluids, compatible with most alkalis, acids, and solvents (when using appropriate materials)
• Stall-free, low pulsation air valve for smooth operation
• Spring-loaded pilot valves for faster changeover and reduced pulsation
• Externally serviceable components for easier maintenance
• Bolted joint design for even sealing pressure and leak-free operation
• Longer diaphragm life compared to competitors
• One-piece center section reduces leaks and maintenance frequency

Applications:
Ideal for transferring chemicals, solvents, paints, coatings, and other industrial fluids in mining, agriculture, manufacturing, and maintenance operations.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure all connections are tight and properly sealed to prevent leaks
• Follow manufacturer guidelines for air supply and fluid compatibility
• Regularly inspect and maintain diaphragms, seats, and balls for wear
• Use appropriate personal protective equipment during installation and maintenance
