The GRACO Husky 1050 Aluminum (1" NPT) Pump is an air-operated double diaphragm pump constructed with an aluminum center section, TPE (thermoplastic elastomer) seats, PTFE balls, and PTFE overmolded diaphragm. It is designed for reliable transfer of fluids such as water, antifreeze, and fuel in industrial and vehicle service applications.

Key Features:

• Pneumatic (air-operated) double diaphragm pump
• Husky 1050, 1" NPT
• Aluminum center section, TPE seats, PTFE balls, PTFE overmolded diaphragm
• Maximum free-flow delivery: 189 L/min (50 gpm)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for standard metal pumps; some configurations may have lower ratings (e.g., 50 psi for certain UL-listed models)
• For use with water, antifreeze, fuel, oil, and waste oil; compatible with fluids containing solids up to 3.2 mm (1/8 in)
• UL-listed for certain models; check specific part number for certification
• Stall-free, low pulsation air valve for smooth and rapid changeover
• Reliable, robust construction for industrial environments
• Easy maintenance and serviceability
• Handles abrasive and viscous fluids with solids
• Low noise operation at lower pressures

Applications:
Industrial fluid transfer, vehicle service (fuel, antifreeze, oil), waste oil handling, and general-purpose pumping in harsh environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate thread sealant for NPT connections
• Check air supply for correct pressure and cleanliness
• Inspect diaphragms and seats regularly for wear and replace as needed
• Follow manufacturer’s guidelines for fluid compatibility and maximum solid size
