Spring-loaded seal Turbo

with circular cross sectionmetalfor aircraft

Overview
Metal turbo seals have been engineered for applications requiring light loading, flexibility and high temperature capability. They can be spring-energized to enhance sealing performance. While primarily used as face seals, they can also be manufactured in axial configurations for specific uses such as gas turbines in power generation.

Applications

• Face and axial turbine shaft seals for flexible, light-load applications
• Energy and power-generation equipment (gas turbines) and other rotating machinery with limited motion, thermal expansion or misalignment

Design & Function

• Primarily designed as face seals; axial configurations available
• Option for spring-energized designs to improve sealing performance
• Engineered to accommodate limited motions due to thermal expansion, misalignment or increased springback
• Dual sealing capability (face & axial) to adapt to varied system geometries and limited motions
