The Husky 1050 is an air-operated double diaphragm pump with an aluminum center section, fluoroelastomer seats, PTFE balls, and PTFE overmolded diaphragm. It is designed for reliable, efficient transfer of water, antifreeze, fuel, and other compatible fluids in industrial and maintenance applications.

Key Features:

• Air-Operated Double Diaphragm Pump
• Husky 1050, 1" NPT
• Aluminum center section, fluoroelastomer seats, PTFE balls, PTFE overmolded diaphragm
• Maximum free flow delivery: 50 gpm (189 lpm)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa)
• Water, antifreeze, fuel, and compatible fluids; handles solids up to 1/8 in (3.2 mm)
• UL listed
• Stall-free low pulsation air valve for smooth, rapid changeover
• Spring-loaded pilot valves for faster changeover and reduced pulsation
• Externally serviceable components
• One-piece center section eliminates leaks and reduces maintenance
• Bolted joint design for even sealing pressure and leak-free operation
• Diaphragm life span up to 5x longer than competitors
• High strength-to-weight ratio and chemical resistance (for polypropylene center section; aluminum is standard for this part number)

Applications:
Industrial fluid transfer, water, antifreeze, fuel, and compatible fluids; suitable for environments requiring robust, leak-free, and low-maintenance pumps

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment and secure bolting of the center section
• Use appropriate thread sealant for NPT connections
• Check for leaks after installation and during initial operation
• Follow manufacturer-recommended maintenance intervals for diaphragm and valve inspection
• Use clean, dry air supply within specified pressure range (20–125 psi)
