Prime Standard Oil Lubricated Seals

Prime Standard Oil Lubricated Seals

Over the years AEGIR-Marine has developed many different types of seal assemblies. Careful engineering by the 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

Options for both PRIME Seal types:

1. On the AFT split type seal all housings and the liner are divisible. This means that there is no need for shaft withdrawal when seals and/or housing parts have to be replaced.
2. When grooves appear on the surface of the liner, we offer the installation of an extra distance ring (spacer) to extend the liner’s lifetime. 
3. To improve the lifetime of stern tube liners, we offer a tungsten coating. This coating can be applied on new and used liners and will be done within required tolerances. Since tungsten coating doesn’t wear over the years, this option is very cost efficient.
