The GRACO Husky 3300A is an air-operated double diaphragm pump designed for heavy-duty industrial applications. It features a robust aluminum construction with stainless steel and polypropylene components, engineered for reliable transfer of abrasive, viscous, or corrosive fluids. This pump is intended for use in demanding environments such as mining, chemical processing, and manufacturing.

Key Features:

• Air-operated double diaphragm pump
• 3300A, 3 inch
• Aluminum center section with stainless steel and polypropylene wetted parts (specific to configuration PA01GA2SSPTPOPT)
• Up to 300 gpm (1,135 lpm)
• Maximum fluid working pressure: 125 psi (8.6 bar) for aluminum and stainless steel center sections
• ANSI/DIN/NPT flange and thread standards
• ATEX configuration available (dependent on specific model and fluid temperature)
• Stall-free, low pulsation air valve for smooth and rapid changeover
• One-piece center section for leak reduction and lower maintenance
• Heavy-duty construction for long service life
• Up to 40% more efficient than comparable pumps
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Spring-loaded pilot valves for faster changeover

Applications:
Suitable for transferring abrasive, viscous, or corrosive fluids in industries such as mining, chemical processing, manufacturing, and agriculture.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, and maintains warranty coverage.
• Install the pump as close as possible to the material source to maximize suction performance
• Minimize suction requirements to maximize pump 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 and outlet port connections
• Rotate the center manifold to change the orientation of inlet or outlet ports as needed
