The GRACO Husky 1050 Aluminum Pump is an air-operated double diaphragm pump designed for industrial fluid transfer. It features a standard aluminum center section, aluminum seats, Santoprene balls, and a Buna-N diaphragm, making it suitable for handling a wide range of fluids including water, antifreeze, and fuels. Its robust construction and efficient design are intended for reliable, leak-free operation in demanding environments.

Key Features:

• Air-operated double diaphragm pump
• Husky 1050, 1" NPT
• Standard aluminum center section, aluminum seats, Santoprene balls, Buna-N diaphragm
• Maximum free-flow delivery: 189 L/min (50 gpm)
• Maximum fluid working pressure: 125 psi (8.6 bar, 0.86 MPa) [Note: Some sources list 100 psi (7 bar, 700 kPa) for specific configurations; confirm for your application]
• Compatible with water, antifreeze, fuel, and other industrial fluids
• UL listed (for some configurations)
• Stall-free low pulsation air valve for smooth and 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
• Long diaphragm life (up to 5x longer than competitors)
• High strength-to-weight ratio and chemical resistance (for plastic center section models; aluminum is robust and corrosion-resistant)

Applications:
Industrial fluid transfer, including water, antifreeze, fuel, and other compatible liquids. Suitable for mining, agriculture, manufacturing, and maintenance operations.

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 this model)
• Use appropriate thread sealant for leak-free installation
• Check air supply for correct pressure and cleanliness
• Inspect diaphragms and balls for wear during installation and maintenance
• Follow manufacturer torque specifications for bolted joints
• Regularly inspect for leaks and wear, and replace worn components promptly
