The GRACO Husky 3300 is a heavy-duty, air-operated double diaphragm pump designed for high-volume fluid transfer applications. It features an aluminum center section, TPE (thermoplastic elastomer) seats, and standard polychloroprene (CR) balls and diaphragms. This pump is engineered for reliable, efficient, and leak-free operation in demanding industrial environments.

Key Features:

• Air-operated double diaphragm pump
• Husky 3300, 3" (76.2 mm) threaded flange
• Aluminum center section, TPE seats, polychloroprene (CR) balls and diaphragms
• Up to 1,135 L/min (300 gpm)
• Maximum working pressure: 8.6 bar (125 psi)
• Compatible with a wide range of fluids and slurries, suitable for industrial, mining, and agricultural applications
• Stall-free, low pulsation air valve for smooth and rapid changeover
• One-piece center section for leak elimination 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
• Up to 40% more efficient than comparable pumps

Applications:
Ideal for transferring high-viscosity materials, slurries, and abrasive fluids in industrial, mining, agricultural, and in-plant manufacturing environments. Suitable for applications requiring high flow rates and reliable, leak-free operation.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment of inlet and discharge connections (3" BSPT or ANSI/DN/NPT as specified)
• Follow manufacturer guidelines for air supply and pressure settings
• Inspect and replace diaphragms, balls, and seats as recommended in the maintenance schedule
• Regularly check for leaks and wear, especially in high-abrasion environments
• Consult the equipment manual for detailed installation and maintenance procedures
