A patented lip design and the patented combination of PTFE sealing lip and sliding bearing in the lip seal element provide the new dry running seal “SeccoLip” from EagleBurgmann with particularly high flexibility. These technical features help the lip seal compensate directly and safely radial deflections of the shafts in agitators, mixers and reactors.
The sliding bearing tracks the complete lip seal element to the shaft movements. Since the lip and bearing are in one element, the sealing gap between the rotating shaft and the sealing lip remains virtually constant and the seal remains tight over the long term. Compensating elements such as O-ring, expansion washer or metal bellows are not required for reliable operation.
The modular seal was specifically designed for the operating conditions in the chemical, pharmaceutical, food industry as well as in water and wastewater technology. One or more sealing elements are combined in different possible arrangements to comply with the requirements.
Connections for a supply system are available. Due to the design features, a rolling bearing is not necessary but is optionally available.
The cartridge design makes the SeccoLip easy to install and safe to use. It is particularly suitable for a sliding velocity of up to 2 m/s (6 ft/s) and a pressure range of -1 to 6 barg.
The seal complies to ATEX, FDA and TA-Luft.
