Melal Bellow Balanced Seal

STS-91 Specially developed for high temperature ranges and sliding velocities. It insulate the flexible element from direct shaft vibration and promotes more positive sealing while significantly extending seal life. Each welded set of plates has a fixed axial movement along the shaft. Pressure capability of the standard seal can be enhanced by using this. It is mainly used in Petrochemical, Thermic Fluid & Refineries.
