The Husky 1050 is an air-operated double diaphragm pump with an aluminum center section, TPE (Hytrel) seats, PTFE balls, and PTFE overmolded diaphragm. It is designed for reliable, low-maintenance transfer of fluids such as water, antifreeze, and fuel in industrial and vehicle service applications.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050, 1" BSPT
• Aluminum center section, TPE (Hytrel) seats, PTFE balls, PTFE overmolded diaphragm
• Maximum free flow: 50 gpm (189 lpm); typical maximum flow: 38 gpm (varies by configuration)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa); typical maximum fluid pressure: 50–100 psi (depending on configuration)
• For use with water, antifreeze, fuel, and compatible fluids; not for use with incompatible chemicals or highly abrasive media
• UL listed
• Stall-free, low pulsation air valve for smooth and rapid changeover
• One-piece center section eliminates leaks and reduces maintenance
• Up to 5 times longer diaphragm life compared to similar pumps
• Spring-loaded, externally serviceable pilot valves for faster changeover and reduced pulsation
• No-lube, no-stall air valve design
• Offered in ATEX configuration for hazardous environments

Applications:
Industrial fluid transfer, vehicle service (fuel, antifreeze, water), general-purpose pumping of compatible liquids

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may void warranties and reduce pump lifespan.
• Ensure proper alignment of inlet and outlet ports
• Use appropriate thread sealant for BSPT connections
• Check for leaks after installation
• Follow manufacturer’s guidelines for air supply and pressure
• Regularly inspect and maintain diaphragms and seals
