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

Key Features:

• Pneumatic Diaphragm Pump
• Husky 1050, 1" NPT
• Aluminum center section, TPE seats, PTFE balls, TPE diaphragm
• Maximum free flow delivery: 50 gpm (189 lpm); typical maximum flow rate: 38 gpm (varies by configuration)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) for standard metal pumps; some configurations list 50–100 psi (0.35–0.7 MPa) for specific applications
• For use with water, antifreeze, fuel, and compatible fluids; maximum solid size: 1/8 in (3.2 mm)
• UL listed
• Stall-free low pulsation air valve for smooth and rapid changeover
• Reliable, robust construction for industrial environments
• Easy maintenance and repair with modular design
• Handles abrasive and viscous fluids with solids up to 1/8 in (3.2 mm)
• Remote aluminum center section for specific installation needs

Applications:
Industrial fluid transfer, vehicle service (fuel, antifreeze, water), mining, agriculture, and other sectors requiring robust, reliable pumping solutions.

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 fittings and hoses rated for the intended fluid and pressure
• Follow manufacturer guidelines for air supply and exhaust port connections
• Regularly inspect and maintain diaphragms, seats, and balls for wear
• Refer to the pump’s ID plate for configuration and part numbers when ordering replacements
• Perform routine maintenance as outlined in the manual
• Use only compatible fluids and avoid exceeding maximum pressure and temperature ratings
• Keep air supply clean and dry to prevent valve and diaphragm damage
• Store spare parts and kits for quick replacement and minimal downtime
