The GRACO 647016 Husky 1050 is an air-operated double diaphragm pump constructed with aluminum (AL) and thermoplastic elastomer (TPE) components. It is designed for the reliable transfer of water, antifreeze, and fuel in industrial applications.

Key Features:

• Pneumatic Diaphragm Pump
• Husky 1050, 1 inch
• Aluminum (AL) and TPE (Hytrel) materials
• Maximum free flow delivery: 50 gpm (189 lpm)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for metal pumps; 100 psi (7 bar, 700 kPa) for AL/TPE model
• Water, antifreeze, and fuel transfer
• UL
• Stall-free, low pulsation air valve for smooth and rapid changeover
• One-piece center section eliminates leaks and reduces maintenance
• Externally serviceable spring-loaded pilot valves
• Bolted joint design for even sealing pressure and leak-free operation
• Diaphragm life up to 5x longer than competitors
• Modular air valve for easy maintenance
• High strength-to-weight ratio and chemical resistance (polypropylene center section in some models)

Applications:
Industrial transfer of water, antifreeze, and fuel; suitable for environments requiring reliable, low-maintenance fluid handling.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment and secure bolting of the pump to prevent leaks
• Use compatible fittings and hoses rated for the intended fluid and pressure
• Follow manufacturer guidelines for air supply and fluid connections
• Regularly inspect diaphragms and valves for wear and replace as needed
• Refer to the product manual for specific installation and maintenance procedures
