The GRACO Husky 1050 is an air-operated double diaphragm pump with an aluminum center section, TPE (thermoplastic elastomer) seats, PTFE balls, and PTFE diaphragm. It is designed for reliable transfer of fluids such as water, antifreeze, and fuel in industrial and commercial applications.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050, 1" NPT
• Aluminum center section, TPE seats, PTFE balls, PTFE diaphragm
• Maximum free flow: 50 gpm (189 lpm) (varies by configuration; some sources list 32 gpm for fuel dispense applications)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) (varies by configuration; some sources list 50 psi for fuel dispense applications)
• Suitable for water, antifreeze, fuel (including gasoline, diesel, fuel oil, lubricating oil), and other compatible fluids
• UL listed for fuels (for certain configurations)
• Stall-free, low pulsation air valve for smooth operation
• One-piece center section reduces leaks and maintenance
• Up to 5 times longer diaphragm life compared to similar pumps
• Spring-loaded, externally serviceable pilot valves for faster changeover and reduced pulsation
• ATEX configuration available for hazardous environments
• 30% more efficient than market leader (for certain configurations)
• 20% increase in fluid flow compared to Husky 1040

Applications:
Industrial and commercial fluid transfer, including water, antifreeze, fuel (gasoline, diesel, fuel oil, lubricating oil), and other compatible fluids. Suitable for fuel dispense applications with appropriate relief valve and configuration.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure correct alignment of inlet and outlet ports
• Use appropriate thread sealant for NPT connections
• Verify air supply pressure and flow rate match pump requirements
• Install relief valve for fuel dispense applications if required
• Regularly inspect and maintain diaphragm, seats, and balls for wear
• Follow manufacturer’s recommended maintenance schedule
• Use only compatible fluids as specified in the manual
• Inspect for leaks and unusual noise during operation
• Replace worn components with genuine GRACO parts
