Graco Husky 3300 Air-Operated Diaphragm Pumps
Description
The Graco Husky 3300 air-operated diaphragm pump features a stall-free low pulsation air valve which provides a smooth and rapid changeover.
The one-piece centre section eliminates leaks and reduces maintenance on the Husky pumps when compared to other diaphragm pumps.
Benefits of the Graco Husky 3300 double diaphragm pumps:
- Overall improved efficiency (up to 40% more efficient).
- The highest fluid flow rate in its class.
- Up to 5 times, longer diaphragm life compared to other air operated diaphragm pumps.
- Expanded material offering to handle endless applications.
- Offered in ATEX configuration..
