Radial displacements and BIO oils

Blade seals installed on turbines must keep the lubricant inside the hub and prevent water contamination.

Travel radials related to wear of the bronze rings (sagging of the blade) forced the seals to a great clearance.

The new environmental standards require more and more the filling of the units by aggressive organic oils to elastomers.

Techoseal DEFENDER Gaskets have specially been developed for this application.
