The GRACO Husky 3300 is a heavy-duty, air-operated double diaphragm pump designed for professional fluid transfer applications, including high-viscosity materials. This specific configuration features a polypropylene pump with an aluminum center section, polypropylene seats, and fluoroelastomer (FKM) balls and diaphragms, making it suitable for handling a wide range of chemicals and abrasive fluids.

Key Features:

• Air-operated double diaphragm pump
• Husky 3300, 3 inch (76.2 mm)
• Polypropylene pump with aluminum center section, polypropylene seats, fluoroelastomer (FKM) balls and diaphragms
• Up to 300 GPM (1,135 LPM)
• 100 psi (0.7 MPa, 6.9 bar) maximum working pressure for polypropylene center section
• Designed for use with a wide range of fluids, including chemicals and abrasive materials
• Stall-free low pulsation air valve for smooth and rapid changeover
• Four-bolt joint design for even sealing and leak-free operation
• Three-piece manifold for installation flexibility
• 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)
• One-piece center section reduces leaks and maintenance

Applications:
Ideal for transferring high-viscosity, abrasive, or chemical fluids in industrial, mining, agricultural, and maintenance environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump.
• 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 torque instructions for manifold assembly to prevent leaks
• Regularly inspect and maintain diaphragms, seats, and balls for wear and replace as needed
