• Husky 3300e, 3-inch
• Stainless steel (SS) seat, aluminum (AL) center, PTFE (PT) ball and diaphragm
• Up to 220 gpm
• Designed for use with a wide range of industrial fluids, including solids, slurries, and abrasives
• ATEX (explosion-proof motor available)
• Up to 80% reduction in energy usage compared to air diaphragm pumps
• Runs dry, self-primes, and stalls under pressure
• Seal-less design for leak-free operation
• Low pulsation without costly dampeners
• Near 0 dB in-plant noise pollution
• Accurately meter fluid with VFD controls
• Modular design using long-life elastomers
• Robust construction for handling solids, slurries, and abrasives

Applications:
Ideal for tough industrial transfer jobs in environments requiring explosion-proof equipment, such as chemical processing, mining, and manufacturing. Suitable for transferring a wide variety of fluids, including those with solids or abrasives.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, especially in hazardous environments.
• Ensure proper alignment and secure mounting to minimize vibration and wear
• Verify electrical connections are suitable for ATEX-rated environments
• Follow all local and industry safety regulations during installation
• Regularly inspect and maintain diaphragms and seals for long service life
