The GRACO 647273 Husky 1050 is an air-operated double diaphragm pump featuring an aluminum center section, stainless steel seats, PTFE balls, and a Santoprene diaphragm. It is designed for reliable, efficient transfer of fluids such as oil, water, antifreeze, and fuel in industrial and vehicle service applications.

Key Features:

• Pneumatic Diaphragm Pump
• Husky 1050, 1" BSPT
• Aluminum center section, stainless steel seats, PTFE balls, Santoprene diaphragm
• Maximum flow rate: 38–50 GPM (varies by configuration and material; for aluminum, typically up to 50 GPM)
• Maximum fluid pressure: 50–125 psi (varies by configuration; for aluminum, up to 125 psi in some models)
• For use with oil, waste oil, water, antifreeze, and fuel
• UL Listed
• Stall-free low pulsation air valve for smooth, rapid changeover
• One-piece center section for leak elimination and reduced maintenance
• Longer diaphragm life (up to 5x longer than competitors)
• Externally serviceable spring-loaded pilot valves
• Bolted joint design for even sealing pressure and leak-free operation
• High strength-to-weight ratio and chemical resistance (when polypropylene center is used; for aluminum, high durability and corrosion resistance)

Applications:
Industrial fluid transfer, oil evacuation, oil transfer, water, antifreeze, and fuel transfer in vehicle service and industrial environments

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment, reducing downtime and maintenance costs.
• Ensure proper alignment and secure bolting of the center section for leak-free operation
• Use recommended air supply pressure and flow rate for best performance
• Regularly inspect diaphragms and valves for wear and replace as needed
• Follow manufacturer guidelines for installation and maintenance to maximize pump life
• Periodically check for leaks and tighten connections as necessary
• Use compatible fluids and avoid exceeding maximum pressure and temperature ratings
• Keep air supply clean and dry to prevent valve and diaphragm damage
