The GRACO Husky 3300 (3 in. NPT) Stainless Steel Pump with Aluminum Center Section, FKM Seats, Balls & Diaphragm is an air-operated double diaphragm pump designed for heavy-duty fluid transfer applications. It is constructed with stainless steel wetted parts, an aluminum center section, and FKM (fluorocarbon) elastomers for chemical resistance. This pump is intended for use in demanding industrial environments where reliability and resistance to aggressive fluids are required.

Key Features:

• Air-operated double diaphragm pump
• Husky 3300, 3 inch (76.2 mm) NPT
• Stainless steel wetted parts, aluminum center section, FKM seats, balls & diaphragm
• Up to 300 gpm (1,135 lpm)
• Maximum fluid discharge pressure: 100 psi (7 bar, 0.7 MPa) (Note: Some listings specify up to 125 psi, but 100 psi is most commonly cited for standard models)
• Compatible with a wide range of fluids, especially aggressive chemicals, due to FKM elastomers and stainless steel construction
• Stall-free low pulsation air valve for smooth and rapid changeover
• One-piece center section eliminates leaks and reduces 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 environments

Applications:
Suitable for transferring aggressive chemicals, industrial fluids, and slurries in industries such as mining, agriculture, chemical processing, and bulk fluid handling.

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 manifold installation and ensure proper grounding of the equipment
• Regularly inspect diaphragms, seats, and balls for wear
• Replace worn components with genuine GRACO parts
• Keep the pump clean and free from debris
• Monitor for leaks and address them promptly
