Applications:
Industrial fluid transfer, including water, antifreeze, fuel, and chemicals. Suitable for mining, agriculture, manufacturing, and other sectors requiring reliable, chemical-resistant 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.
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose
• Ensure proper alignment and secure mounting of the pump
• Use compatible hoses and fittings rated for the intended fluid and pressure
• Regularly inspect and maintain seals, diaphragms, and connections for leaks or wear
• Consult the GRACO Husky 1050 manual for specific installation and maintenance procedures
