• Air-operated double diaphragm pump
• Husky 3300, 3 in. NPT (76.2 mm)
• Stainless steel body, aluminum center section, SP (Santoprene) seats, PTFE balls, SP diaphragm
• Up to 300 gpm (1,135 lpm)
• Max air pressure: 125 psi; Max fluid pressure: 125 psi (0.86 MPa)
• Compatible with a wide range of fluids, including corrosive and abrasive materials
• Four-bolt joint design for even sealing and leak-free operation
• Three-piece manifold for installation flexibility
• Modular stall-resistant air valve design
• Spring-loaded pilot valves for faster changeover
• One-piece center section (in some configurations) to reduce leaks and maintenance
• Heavy-duty construction for long service life
• Up to 5 times longer diaphragm life compared to other air-operated diaphragm pumps
• Overall improved efficiency (up to 40% more efficient)

Applications:
Ideal for transferring fluids in industrial, chemical, mining, agricultural, and manufacturing environments where chemical resistance, durability, and high flow rates are required.

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 performance
• Minimize suction requirements to maximize pump performance
• Use grounded, flexible fluid hoses to reduce the risk of static sparking
• Install a fluid drain valve near the fluid outlet
• Install a shutoff valve in the fluid outlet line
• Follow torque instructions for manifold assembly
• Remove and rotate the center manifold to change the orientation of inlet or outlet ports as needed
