Non-contact and contact seals in comparison
Advantages of non-contact seals
Technical advantages
No wear
Rated for high rotating speeds
Sealing efficiency is independent from direction of rotation
No abrasion, no contamination
Thermal advantages
No frictional heat increase
No thermal effects to the surrounding application
Functional advantages
Maintenance free
Constant sealing efficiency during operation
No adjustment required
No lubrication required (approved for dry operation)
Economic advantages
No hardening or grinding of mating parts
Unlimited lifetime – no replacement due to the non-contact design
Cost saving component instead of expensive self made labyrinth
Less maintenance results in higher machine yield
No frictional loss results in reduced demand to engine output
