Labyrinth Ring Seal
The Labyrinth Ring Seal is a non-contact, frictionless solution for turbo expanders. Gas passes through sequential teeth on the seal body, creating pressure drops at each stage. With 6–20 stages, sealing improves with more teeth. Non-contact operation ensures zero wear and minimal maintenance, making it ideal for customers seeking reliability and long service life.

Key Advantages
1. Simple, Reliable, Non-Contact Design
The Labyrinth Ring Seal is a non-contact, frictionless solution for turbo expanders. Gas passes through sequential teeth on the seal body, creating pressure drops at each stage. With 6–20 stages, sealing improves with more teeth. Non-contact operation ensures zero wear and minimal maintenance, making it ideal for customers seeking reliability and long service life.
2. Handles Extreme Temperatures and Harsh Conditions
Our seal works in both cryogenic and high-temperature environments, from -150°C to 450°C. Unlike elastic or brush seals, it is resistant to dust and impurities, maintaining robust performance even in industrial conditions.
3. Precision Manufacturing for Optimal Performance
We employ 5-axis CNC machining to achieve high tooth accuracy and uniform gaps. Material selection is customized: aluminum alloys for cryogenic use, stainless steel or superalloy for high-temperature applications. Complete surveying and manufacturing services ensure perfect fit and performance.
