The GRACO 649178 is a Husky 1050 air-operated double diaphragm pump with a conductive polypropylene (PP) center section and center flange. It is designed for safe, reliable transfer of fluids, especially where static electricity buildup is a concern, and is commonly used in industrial, chemical, and process applications.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050, 1-inch flange
• Conductive polypropylene (PP) center section, PP seats, PTFE balls, PO diaphragm (specific to 649177; 649178 likely similar but confirm with supplier)
• 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, especially those requiring static dissipation
• ATEX certification available (dependent on fluid temperature and configuration)
• Stall-free, low pulsation air valve for smooth operation
• Modular air valve for easy maintenance
• Reliable, robust construction for demanding environments
• Suitable for handling solids up to 1/8 inch (3.2 mm)
• Maximum pump speed: 280 cycles per minute
• Displacement per cycle: 0.17 gal (0.64 liters)
• Maximum suction lift: 16 ft (4.9 m) dry, 29 ft (8.8 m) wet

Applications:
Ideal for transferring chemicals, solvents, and other industrial fluids where static dissipation is required. Commonly used in chemical processing, paint, coatings, and general industrial fluid transfer.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and safety.
• Ensure all connections are secure and leak-free before operation
• Follow all safety instructions in the manual
• Use appropriate personal protective equipment (PPE) during installation and maintenance
• Regularly inspect diaphragms, balls, and seats for wear and replace as needed
• Install in a location with adequate ventilation and access for maintenance
