Labyrinth Seal for a Reciprocating Compressor Selection Process: Four Key Thermal Properties

Torlon and PEEK Polymer Labyrinth Seals Choice?

When selecting the material for a labyrinth seal to be used in a reciprocating compressor, thermal PEEK-Torlon-seal-reciprocating-compresor.jpgproperties can be a major concern.  Since plastics behave differently from metals, there are certain thermal properties that you need to consider when using a thermoplastic labyrinth seal.  In this article, we are going to look at four key thermal properties you need to investigate, focusing on two of the most common choices for polymer labyrinth seals:  Torlon and PEEK.

While most people think of labyrinth seals as a type of rotary seal, they also have applications for non-rotating sealing. 

An excellent example of a non-rotary application is to provide a non-contact seal against high pressure while sealing in oil during compression strokes in reciprocating compressors.  The first reciprocating compressor with a labyrinth seal was built in 1935, and this type of reciprocating compressor is known as a labyrinth compressor.  Although the technology has been modernized and improved over time, some things remain the same – including the benefits.
