The GRACO Husky 3300 is a heavy-duty, air-operated double diaphragm pump designed for industrial fluid transfer. It features an aluminum center section, TPE seats, polychloroprene weighted balls, and a polychloroprene standard diaphragm. This pump is engineered for reliable, leak-free operation and is suitable for handling a wide range of fluids, including those with solids, in demanding environments.

Key Features:

• Air-operated double diaphragm pump
• Husky 3300, 3 inch (76.2 mm) connections
• Aluminum center section, TPE seats, polychloroprene weighted balls, polychloroprene standard diaphragm
• Up to 1,136 L/min (300 gpm)
• Maximum fluid pressure: 8.6 bar (125 psi)
• Compatible with a wide range of fluids, including those with solids up to 12.7 mm
• Stall-free low pulsation air valve for smooth and rapid changeover
• One-piece center section for leak-free operation and reduced maintenance
• Four-bolt joint design for even sealing pressure
• Modular, heavy-duty construction for durability
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Improved efficiency (up to 40% more efficient)
• Faster changeover with spring-loaded pilot valves

Applications:
Industrial fluid transfer, including abrasive, viscous, and solids-laden fluids; suitable for mining, agriculture, chemical processing, and general industrial applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Install the pump as close as possible to the material source to minimize suction requirements and maximize performance
• Use grounded, flexible fluid hoses to reduce the risk of static sparking
• Install a fluid drain valve near the fluid outlet and a shutoff valve in the fluid outlet line
• Follow manufacturer torque instructions for manifold assembly
• Regularly inspect and maintain diaphragms, seats, and balls for wear and tear
