✦ Synopsis

between the bearing and the dry gas seal cavity. The design accommodates either direction of shaft rotation and it also incorporates a carbon bushing segment design with selfadjusting hydro-pads.

The Type 93FR is based on non-contacting operation. It has a floating ring design that incorporates a non-contacting carbon bushing which is designed to prevent oil migration, and also help minimise wear and heat generation under normal running conditions. This promotes long service life and enhanced reliability.

The seal runs at a low-pressure differential that helps reduce gas consumption, while the self-centring mechanism minimizes wear, even during upset conditions. It can accommodate either direction of shaft rotation and the seal can be retrofitted to many traditional separation seal applications.
