The best solution for your ship

Each ship is unique an,d therefore, requires a unique solution. When asked to provide a retrofit AEGIR takes all things into consideration:
What is technically possible? What are your specific needs? What is your budget?

Choosing the best fit possible is our starting point.
Being a make-independent supplier we can supply you with those parts that fit your ship best. We never renew for the sake of renewing. First we check if we can reuse parts.
And yes, our PRIME Seals are class approved and properly fitting seals, but we will not impose our seals. We advise, you decide.

Specifications

AEGIR-Marine Prime Standard

The PRIME AFT seal consists of three sliding connections between PRIME seal rings and a revolving liner (see the illustration).

Offering more options
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 can be applied on new and used liners. Since tungsten coating doesn’t wear, this option is very cost efficient.

PRIME Standard Secure Seal

The PRIME AFT seal consists of three sliding connections between PRIME seal rings and a revolving liner (see the illustration.). In addition an extra seal is installed: Seal #3S. This seal points towards the stern tube and when seal ring 3 is leaking, seal#3S will take over its job.

Offering more options
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.

PRIMAIR, the most reliable sealing system

The air seal technology in PRIMAIR physically separates the stern tube oil from the sea through an air space and has a drain line that goes back to the engine room. Cross contamination is, therefore, not possible.
The system is engineered to discharge air through the seal box. The air pressure varies depending on the outside seawater pressure, while the airflow is stable: reducing wear on seal ring and liner.  

PRIMAIR meets the VGP law requirements even when using conventional lubricants.

AEGIR-Marine can supply spares suitable for existing systems or retrofit your existing system using PRIMAIR in the most cost-effective way.

PRIME Blue, the water lubricated seal

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 your 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. Seal assemblies are supplied with one spare seal. This can be installed by your own engineers. Prime blue seals can be serviced without docking.
