The Arlon 4020 labyrinth seal uses proprietary thermoplastic technology, has a controlled thermal expansion over a wide range of temperatures, and has a tooth profile that make it cost-effective and long-lasting.

Customer test results show up to a 1.5% gain in efficiency compared to traditional seals, correlating with field tests and predictions from FEA analysis.

Non-contacting labyrinth seals reduce leakage in centrifugal applications. This is accomplished by restricting flow through a series of chambers formed between the rotating element while the teeth control the passage of the media.

Greene Tweed’s labyrinth seals deliver high performance due to the combination of custom-engineered tooth designs and high-performance PEEK thermoplastic materials. The materials reduce friction and eliminate galling, which extends the seal’s life and lowers maintenance costs. This optimized thermal expansion allows for retrofit and like-for-like replacement of conventional metallic designs.

The erosion and corrosion resistance make the Arlon 4020 ideal for severe sealing applications, including those with high acid, mercury content, or high-velocity media. Other applications include oil and gas production and transportation, air separation units, chemical industry, fertilizer plants, carbon capture and storage, and industrial applications.
