PEEK labyrinth seals are non-contact dynamic sealing devices that restrict medium leakage in high-speed rotating equipment by utilizing a specific tooth profile to dissipate fluid energy. Compared to traditional metal seals, PEEK allows for significantly tighter clearances, effectively minimizing leakage and extending overall service life.

Key Advantages:

• Precision Clearance Control: Enables small radial clearances of 0.08-0.50mm (40-50% smaller than aluminum alloy), directly reducing leakage rates by 30-60%.

• Extreme Temperature Resistance: Withstands continuous operating temperatures up to 260°C and short-term exposure up to 300°C.

• Durability & Stability: Sustains minimal wear during transient contact without clearance enlargement, and offers robust chemical resistance to acids, alkalis, and organic solvents.

• Lightweight & Extended Lifespan: Features a low density of 1.32g/cm³ to reduce rotor load, while delivering a service life 2-3 times longer than metal labyrinth seals.
