AEGIR’s PRIME Blue assembly is a reliable, durable and proven pollution free seal system for vessels with water-lubricated bearings. This type of seal is the easiest seal to use on the market. Maintenance, including changing the seal, can be done by own engineers while the vessel is in the water. Seals come in a partial split version as standard, but are also available as fully split upon request.
The PRIME Blue seal consists of a rubber lip seal that rotates with the shaft. The lip seal rotates against a stationary mating ring made of chrome steel. The seal casing is made of cast bronze. An inflatable seal for emergency and maintenance purposes is installed in the housing. Seal assemblies are supplied with one spare seal, which is installed around the shaft ready for installation. This can be installed by own engineers. Prime blue seals can be serviced without docking. Prime Blue is class approved by all major classification societies. With this water lubricated seal we avoid to have any oil leakage from the stern seal.
