The Supreme SeaGuard Ventus is an air-type seal. The Supreme SGV seal consists of four lip seals which are clamped in housing parts. This seal ensures zero-emissions of oil, zero inward water leakage and guarantees optimum service life. This promise is backed by verification from DNV GL: the Supreme SeaGuard Ventus may be used with mineral oil in waters covered by VGP regulations. In addition, Lagersmit offers a five-year warranty (ask us for details). Furthermore, the user is able to monitor the condition of the seal at any given moment. The Condition Monitoring makes your propulsion system even more reliable.
How it works?
It works the same as the Supreme Ventus, except there are four lip seals. The chamber between the two oil-repellent lip seals is filled with oil from the L.O. tank. This way the pressure on both sides of the fourth lip seal remains equal. By closing-off the oil supply to this chamber, this 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 fourth seal to work.
