The GRACO 649202 is an air-operated double diaphragm pump featuring a conductive polypropylene (PP) center section, end flange, and PP seats, with PTFE balls and a polyolefin (PO) diaphragm. It is designed for safe, efficient transfer of fluids in industrial applications, especially where static electricity or chemical compatibility is a concern.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050, 1 inch (25.4 mm) flange
• Conductive polypropylene (PP) center section and end flange, PP seats, PTFE balls, PO 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 fluids including antifreeze, detergents, motor oil, hydraulic fluid, cutting oil, and water
• Stall-free, low pulsation air valve for smooth and rapid changeover
• 30% more efficient than market leader
• Up to 5 times longer diaphragm life compared to other double diaphragm pumps in its class
• Expanded material offering for diverse applications
• Reliable, easy to maintain, and robust for demanding industrial environments

Applications:
Industrial fluid transfer, including antifreeze, detergents, motor oil, hydraulic fluid, cutting oil, and water. Ideal for applications requiring static dissipation and chemical resistance.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump.
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose (use Fluid Pressure Relief Kit GR112119 for plastic pumps)
• Ensure proper alignment and secure mounting of the pump
• Follow manufacturer guidelines for air supply and fluid connections
• Regularly inspect and maintain diaphragms, balls, and seats for wear and proper function
