PEEK Labyrinth Seals

_______________________________________________________________________________________________________________________________________________________________________

PEEK labyrinth seals are advanced dynamic sealing components engineered to prevent fluid leakage and contaminant ingress by utilizing a complex maze-like structure of sealing teeth arranged around a rotating shaft. Manufactured from high-performance polyetheretherketone (PEEK), these seals combine exceptional chemical resistance, wear resistance, and thermal stability, making them suitable for a wide range of demanding applications including compressors, gas turbines, pumps, and industrial machinery.

The labyrinth design creates a series of tortuous paths and expansion chambers that reduce pressure and velocity of the fluid or gas attempting to pass through, effectively throttling flow and minimizing leakage without direct contact between rotating and stationary parts. This non-contact feature reduces wear, eliminates the need for lubrication, and allows for thermal expansion without compromising seal integrity.

PEEK material enhances these seals by providing outstanding resistance to harsh chemicals, oils, and solvents, as well as maintaining mechanical strength and dimensional stability at elevated temperatures up to 260°C (500°F). The seals are available in various configurations such as smooth, zigzag, stepped, and honeycomb tooth profiles, and can be custom engineered to meet specific clearance and performance requirements.

Additional benefits of PEEK labyrinth seals include:

Rub Tolerant Fixed Tooth Design: Allows minimal clearance and controlled contact that deflects to prevent wear and rotor damage.

Corrosion and Erosion Resistance: Ideal for harsh environments including chemical processing and energy sectors.

Low Friction & Long Service Life: Reduces maintenance and downtime by minimizing wear and heat generation.

Lightweight and Compact: Simplifies installation and reduces equipment weight.

Versatile Applications: Used in steam turbines, gas turbines, compressors, blowers, and hydraulic systems.

By choosing PEEK labyrinth seals, industries benefit from reliable, efficient sealing solutions that outperform traditional metal or elastomeric seals, especially in high-temperature, high-pressure, and chemically aggressive environments. Their proven performance extends equipment life, reduces leakage, and improves operational efficiency.

For applications where contamination control, leakage prevention, and durability are critical, PEEK labyrinth seals offer an optimal balance of advanced material properties and innovative design.
