Rotating Equipment: How to Improve Labyrinth Seal Performance

Labyrinth seals are mechanical seals used to reduce flow between the stages of centrifugal compressors. Selecting the right material for a labyrinth seal is therefore a critical aspect in optimising the overall efficiency of the machine. This whitepaper provides an introduction to the most common thermoplastic materials selected for labyrinth seals and their key advantages over aluminium, including case studies, technical data, and material compatibility information.
