The GRACO 652426 Husky 3300 is an air-operated double diaphragm pump with a polypropylene (PP) fluid section and center section, designed for high-flow fluid transfer in industrial applications. It features Geolast (GE) seats, balls, and diaphragms for enhanced chemical resistance and durability. The pump is engineered for efficient, reliable, and low-maintenance operation in demanding environments.

Key Features:

• Air-operated double diaphragm pump
• Husky 3300, 3 inch (80 mm) inlet/outlet, 300 gpm (1,135 lpm) flow rate
• Polypropylene (PP) fluid section and center section; Geolast (GE) seats, balls, and diaphragms; PTFE manifold O-rings
• Up to 300 gpm (1,135 lpm)
• Compatible with a wide range of industrial fluids, especially those requiring chemical resistance
• No certification (ATEX configuration available for other models, but not this specific configuration)
• Stall-free low pulsation air valve for smooth changeover
• One-piece center section to prevent leaks and reduce maintenance
• Up to 40% more efficient than comparable pumps
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Modular stall-resistant air valve design
• Heavy-duty construction for demanding applications

Applications:
Ideal for transferring a wide range of industrial fluids, including chemicals, solvents, and abrasive materials, in industries such as mining, agriculture, manufacturing, and processing. Suitable for applications requiring high flow rates and chemical resistance.

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 and a shutoff valve in the fluid outlet line
• Follow torque instructions for inlet/outlet port connections
• Regularly inspect and maintain diaphragms, seats, and balls for wear and chemical compatibility
