The Husky 3300 is a heavy-duty, air-operated double diaphragm pump designed for reliable fluid transfer in demanding industrial environments. This specific configuration features a polypropylene pump with an aluminum center section, Santoprene seats, TPE balls, and a Santoprene diaphragm, 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, Santoprene seats, TPE balls, Santoprene diaphragm
• Up to 1,135–1,136 L/min (approx. 300 gpm)
• Maximum working pressure: 100 psi (0.7 MPa, 6.9 bar) for polypropylene pumps with polypropylene center section; for this configuration (aluminum center section), check with manufacturer for exact rating, but likely similar to aluminum models (up to 125 psi / 8.6 bar)
• Compatible with a wide range of chemicals and abrasive fluids; suitable for industrial, mining, and agricultural applications
• Stall-free low pulsation air valve for smooth and rapid changeover
• One-piece center section for leak reduction and lower maintenance
• Modular, heavy-duty construction for reliability and long service life
• Large flow paths for high-viscosity materials
• Four-bolt joint design for even sealing and leak-free operation

Applications:
Ideal for transferring chemicals, slurries, and abrasive fluids in industrial, mining, and agricultural settings. Suitable for applications requiring robust, maintenance-friendly pumps.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
• 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 static sparking risk
• 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
