The GRACO Husky 3300 is a heavy-duty, air-operated double diaphragm pump designed for industrial fluid transfer. It features an aluminum center section, acetal seats, and polychloroprene standard balls and diaphragms, making it suitable for handling a wide range of chemicals and abrasive fluids in demanding environments.

Key Features:

• Air-operated double diaphragm pump
• Husky 3300, 3" (76.2 mm) inlet/outlet
• Aluminum center section, acetal seats, polychloroprene standard balls and diaphragms
• Up to 1,135–1,136 L/min (300 gpm)
• Maximum working pressure: 8.6 bar (125 psi)
• Compatible with a wide range of chemicals and abrasive fluids; available in aluminum, polypropylene, and stainless steel configurations
• Stall-free, low pulsation air valve for smooth and rapid changeover
• One-piece center section for leak-free operation and reduced maintenance
• Modular, stall-resistant air valve design
• Heavy-duty construction for long service life
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Improved efficiency (up to 40% more efficient)
• Four-bolt joint design for even sealing pressure and leak-free operation
• Three-piece manifold for increased installation flexibility

Applications:
Ideal for transferring chemicals, slurries, and abrasive fluids in industries such as mining, agriculture, manufacturing, and wastewater treatment. Suitable for applications requiring high flow rates and robust construction.

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
• Install a shutoff valve in the fluid outlet line
• Follow torque instructions for manifold assembly to prevent leaks
• Regularly inspect and maintain diaphragms, seats, and balls for wear and replace as needed
