The GRACO 649319 Husky 1050 is an air-operated double diaphragm pump featuring a conductive polypropylene fluid section, acetal seats, PTFE balls, and a PTFE overmolded diaphragm. It is designed for safe, efficient transfer of fluids in industrial environments, especially where static electricity or hazardous materials are a concern.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050, 1 inch (25.4 mm) end flange
• Conductive polypropylene (center section and fluid path), 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)
• Compatible with a wide range of industrial fluids, including those requiring static dissipation
• Stall-free, low pulsation air valve for smooth and rapid changeover
• One-piece center section reduces leaks and maintenance
• Conductive polypropylene construction for static dissipation
• PTFE overmolded diaphragm for chemical resistance and durability
• Efficient and reliable operation in demanding environments

Applications:
Ideal for transferring water, antifreeze, fuels, and other industrial fluids in environments where static electricity or hazardous materials are present. Suitable for mining, agriculture, chemical processing, and general industrial applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and safety.
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose (GRACO recommends using Fluid Pressure Relief Kit GR112119 for Husky 1050 plastic pumps)
• Ensure all connections are secure and compatible with the pump’s end flange and fluid path materials
• Follow GRACO’s installation and maintenance guidelines for best results
• Regularly inspect diaphragms, seats, and balls for wear and replace as needed
