- Extra safety due to its redundant lip seal
- Effective separation of water and lubricants
- Available in split type
How it works
The chamber between the two oil-repellent lip seals is pressurised by the stern tube header tank. This way the pressure on both sides of the fourth lip seal remains equal. By closing off the oil supply to this chamber, the fourth lip seal can be used as a new oil-repellent lip seal. In case of leakage, docking and maintenance can be postponed by putting this redundant (fourth) lip seal to work. With the split version, it is not necessary to pull the shaft during dry dock. The Supreme SeaGuard is available for shaft diameters from 116 to 1150 millimetres.

The Supreme SeaGuard consists of high-quality bronze housing parts, a stainless steel liner, two oil-repellent and two water-repellent rubber (NBR) lip seals.
