Prime Blue Water Lubricated Seals

Over the years AEGIR-Marine has developed many different types of seal assemblies. Careful engineering by our R&D department has led to spare parts as well as complete seal assemblies suitable for renowned makes like Wärtsilä, B+V Industries and Kemel. By applying modern technology and consistently choosing the best materials our seal assemblies meet the highest degree of quality and reliability.

The water lubricated PRIME Blue



The design of the PRIME Blue type seal is very straightforward. It consists of a rubber lip seal rotating 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 your own engineers.

Competitively priced and certified

Spare parts are price competitive compared to other water-lubricated seals. All PRIME Blue spares are available on short notice. Class approval by most major classification societies is available.

No problem, the Prime blue can be serviced afloat in a matter of hours. Just inflate the emergency seal (and for a second barrier use dive assistance to cofferdam the Sterntube) then swap out the seal ring. Note that the spare is carried on the shaft, so no specialist hot bonding equipment required.

Does my forced seawater lubrication to the seal require filtration?

Yes, we recommend 150-micron filtration.

I would like to fit an Aegir Prime Blue seal but don’t want to pull the tail shaft. Is this possible.

Yes. The Prime Blue can be supplied split. That means every component is split and ready to be assembled ‘around the shaft’.
