The most reliable sealing system. AEGIR’s next generation stern tube sealing technology physically seals the stern tube oil from the sea via an air space.
AEGIR-Marine is a manufacturer and supplier of high-quality spare parts. AEGIR-Marine PRIME Parts® is their own make for stern tube seals, bearings, liners, O-rings and many more propulsion spares. The R&D department is responsible for all engineering and development.
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 the seal assemblies meet the highest degree of quality and reliability
PRIMAIR is a very advanced sealing system. ‘Air Seal’ technology physically separates the stern tube oil from the sea via an air space and has a drain line back to the engine room to drain leaked fluids and prevent cross contamination in event of a seal ring failure.
Variable air pressure. The PRIMAIR system works based on ‘Constant Air Flow/Variable Pressure’- technology. This system is engineered to discharge air through the seal box. The air pressure varies while the air flow is stable. The air pressure will vary to keep in sync with the outside seawater pressure (seawater pressure will vary not only with vessel draft but also wave conditions, i.e. swells).
Reducing wear on seal ring and liner. The variable pressure method maintains a perfect pressure balance inside the seal box. This perfect pressure balance prevents flexing of the seal ring thereby reducing stress on the seal ring material. It also reduces wear on the seal ring and chrome steel liner because the pressure on the seal rings is lower than within a conventional system. This combination greatly improves seal reliability.
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 Prime Standard or Prime Standard Secure.
