• Air-operated double diaphragm pump
• Husky 3300, 3 inch (76.2 mm)
• Aluminum center section, TPE seats, Buna-N balls, TPE diaphragms
• Up to 1,136 L/min (300 gpm)
• Maximum fluid pressure: 8.6 bar (125 psi)
• Compatible with a wide range of industrial fluids and slurries; available in various material configurations for different applications
• Stall-free low pulsation air valve for smooth and rapid changeover
• Four-bolt joint design for even sealing and leak-free operation
• Modular, stall-resistant air valve design
• One-piece center section reduces leaks and maintenance
• Heavy-duty construction for reliability and long service life
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Improved efficiency (up to 40% more efficient)

Applications:
Ideal for transferring fluids and slurries in industries such as mining, agriculture, chemical processing, and manufacturing. Suitable for handling fluids with solids up to 12.7 mm in size.

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
