The GRACO Husky 1050 is an air-operated double diaphragm pump designed for industrial fluid transfer. This specific configuration features an aluminum center section with pulse count capability, stainless steel (S/S) seats, PTFE balls, and a PTFE overmolded diaphragm. It is intended for reliable, efficient transfer of water, antifreeze, fuels, and other compatible fluids in demanding environments.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050, 1" NPT
• Aluminum center section, stainless steel seats, PTFE balls, PTFE overmolded diaphragm
• Maximum free flow delivery: 50 gpm (189 lpm) (varies by configuration; some sources list 32 gpm for specific setups)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) (some sources list 100 psi for certain configurations)
• Suitable for water, antifreeze, fuels (including gasoline, diesel, fuel oil), and lubricating oils; UL listed for fuels
• UL listed for use with fuels
• Stall-free, low pulsation air valve for smooth and rapid changeover
• Up to 5 times longer diaphragm life compared to other double diaphragm pumps in its class
• 30% more efficient than market leader
• 20% increase in fluid flow compared to Husky 1040
• Pulse count feature for monitoring and control
• Robust construction for demanding environments

Applications:
Industrial fluid transfer, fuel dispense, water and antifreeze transfer, lubrication systems, and other applications requiring reliable, efficient pumping of compatible fluids

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 is clean and within recommended pressure range
• Follow manufacturer’s guidelines for diaphragm and seat installation
• Regularly inspect and maintain diaphragms, seats, and balls for wear
• Perform routine maintenance as per GRACO recommendations
• Use only compatible fluids as specified in the manual
• Monitor pulse count for maintenance scheduling and troubleshooting
