The GRACO 649309 is a conductive polypropylene air-operated double diaphragm pump designed for safe, reliable fluid transfer in industrial environments. It features a conductive polypropylene end flange and center section, stainless steel seats and balls, and a PTFE diaphragm for chemical resistance and durability. This pump is intended for use in applications requiring static dissipation and robust material handling.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 1050, 1-inch
• Conductive Polypropylene (end flange and center section), Stainless Steel (seats and balls), PTFE (diaphragm)
• Maximum free flow delivery: 50 gpm (189 lpm)
• Maximum fluid working pressure: 100–125 psi (7–8.6 bar, 0.7–0.86 MPa) depending on configuration
• Compatible with a wide range of industrial fluids, including those requiring static dissipation
• UL listed (varies by configuration; check specific model for certification)
• Stall-free, low pulsation air valve for smooth and rapid changeover
• One-piece center section eliminates leaks and reduces maintenance
• Four-bolt joint design for even sealing pressure and leak-free operation
• Multiple ports for installation flexibility
• DataTrak® option for runaway protection and material usage tracking
• Up to 5x longer diaphragm life for less maintenance and downtime

Applications:
Industrial fluid transfer, including water, antifreeze, fuel, and chemicals requiring static dissipation and chemical resistance. Suitable for mining, agriculture, and other heavy-duty environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with existing equipment.
• Ensure all connections are secure and leak-free before operation
• Follow manufacturer guidelines for air supply and pressure settings
• Regularly inspect diaphragms, seats, and balls for wear and replace as needed
• Use appropriate personal protective equipment during installation and maintenance
• Perform routine inspections and maintenance as recommended in the manual
• Replace worn or damaged components with genuine GRACO parts
• Keep the pump clean and free from debris to prevent clogging and wear
