The GRACO 649219 is a conductive polypropylene air-operated double diaphragm pump designed for safe and efficient transfer of fluids, especially where static electricity or chemical compatibility is a concern. It features a conductive polypropylene end flange and center section, acetal seats, PTFE balls, and a PTFE overmolded diaphragm, making it suitable for handling a wide range of industrial fluids.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050
• Conductive polypropylene end flange and center section, acetal seats, PTFE balls, PTFE overmolded diaphragm
• Maximum free flow delivery: 50 gpm (189 lpm)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa)
• Suitable for a wide range of industrial fluids, especially where static electricity or chemical compatibility is required
• Stall-free low pulsation air valve for smooth and rapid changeover
• Conductive polypropylene construction for static dissipation
• PTFE overmolded diaphragm for chemical resistance
• Acetal seats and PTFE balls for durability and compatibility
• Reliable, low-maintenance design

Applications:
Ideal for transferring fluids in industries such as chemical processing, mining, agriculture, and manufacturing where static electricity or chemical compatibility is a concern. Suitable for handling fluids with solids up to 1/8 inch (3.2 mm) in size.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump.
• Ensure proper alignment of all components during assembly
• Use recommended gaskets and seals for leak-free operation
• Follow manufacturer guidelines for air supply and fluid connections
• Regularly inspect and maintain diaphragms and seats for wear
