The GRACO Husky 3300 is an air-operated double diaphragm pump designed for heavy-duty industrial applications. It features an aluminum center section, TPE (thermoplastic elastomer) seats, Santoprene balls (note: some sources specify Acetal balls, but Santoprene is sometimes used in similar models; for this specific part, confirm with manufacturer), and TPE diaphragms. It is engineered for reliable, efficient transfer of a wide range of fluids, including chemicals and abrasive materials.

Key Features:

• Air-operated double diaphragm pump
• Husky 3300, 3" (76.2 mm) ANSI/DIN/BSPT
• Aluminum center section, TPE seats, TPE diaphragm, Santoprene balls (note: some sources specify Acetal balls; confirm with manufacturer for this part number)
• Up to 1,136 L/min (300 gpm)
• Maximum fluid pressure: 8.6 bar (125 psi)
• Compatible with a wide range of fluids, including chemicals and abrasive materials
• Stall-free low pulsation air valve for smooth, rapid changeover
• One-piece center section reduces leaks and maintenance
• Heavy-duty construction for reliability
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Modular, stall-resistant air valve design
• Expanded material offering for diverse applications

Applications:
Transfer of chemicals, abrasive fluids, and other industrial liquids in mining, agriculture, manufacturing, and other heavy-duty environments.

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 maximize suction performance
• Minimize suction requirements to enhance pump efficiency
• Use grounded, flexible fluid hoses to reduce static sparking risk
• Install a fluid drain valve near the fluid outlet
• Install a shutoff valve in the fluid outlet line
• Follow torque instructions for manifold assembly
• Regularly inspect diaphragms, seats, and balls for wear
• Ensure proper grounding to prevent static sparking
• Use only recommended replacement parts for maintenance
