The GRACO 652997 Husky 3300S is a heavy-duty air-operated diaphragm pump constructed primarily from stainless steel, with PTFE (PT), polypropylene (PO), and aluminum (A) components. It is designed for high-volume, reliable transfer of a wide range of fluids, including abrasive, viscous, and corrosive materials, making it suitable for demanding industrial applications.

Key Features:

• Air-operated diaphragm pump
• 3300S (3" Stainless Steel, PT/PO/A)
• Stainless steel body, PTFE, polypropylene, and aluminum components
• Up to 300 GPM (1,135 LPM)
• Maximum fluid pressure: 0.7 MPa (approx. 100 psi)
• Compatible with a wide range of fluids, including abrasive, viscous, and corrosive materials
• Stall-free low pulsation air valve for smooth, rapid changeover
• One-piece center section eliminates leaks and reduces maintenance
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Modular, stall-resistant air valve design
• Heavy-duty construction for reliability and long service life
• Expanded material offering for handling numerous applications

Applications:
Ideal for transferring fluids in industrial, mining, chemical, and agricultural environments where reliability, durability, and resistance to harsh materials are required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump.
• Install the pump as close as possible to the material source to maximize suction performance
• 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 inlet/outlet port connections
• Ensure the equipment is properly grounded
• Regularly inspect diaphragms and seals for wear
• Check for leaks and tighten connections as needed
• Follow manufacturer’s maintenance schedule
