The GRACO 647063 Husky 1050 is an air-operated double diaphragm pump featuring a standard aluminum center section, aluminum seats, Buna-N balls, and a TPE (Hytrel) diaphragm. It is designed for reliable, efficient transfer of fluids, including those with small solids, in industrial and maintenance applications.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050, 1" NPT
• Standard aluminum center section, aluminum seats, Buna-N balls, TPE (Hytrel) diaphragm
• Maximum free-flow delivery: 189 L/min (50 gpm)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa); Maximum air pressure: 50 psi (0.35 MPa)
• For use with a wide range of fluids, including those with solids up to 3.2 mm (1/8 in)
• UL listed
• Stall-free low pulsation air valve for smooth, rapid changeover
• Spring-loaded pilot valves for faster changeover and reduced pulsation
• Externally serviceable
• Diaphragm life span up to 5x longer than competitors
• One-piece center section eliminates leaks and reduces maintenance
• Bolted joint design for even sealing pressure and leak-free operation

Applications:
Ideal for fluid transfer in industrial, mining, agricultural, and maintenance environments. Suitable for handling fluids with small solids, including fuels, chemicals, and process liquids.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment of inlet and outlet connections (1" NPT for aluminum models)
• Check for correct air supply (maximum 50 psi, 0.35 MPa)
• Inspect all seals and diaphragms before installation
• Follow manufacturer’s guidelines for maximum suction lift (16 ft dry, 29 ft wet)
• Regularly inspect and maintain diaphragms and seals for best performance
