How it works

Outboard water will be pumped through water-lubricated journal bearings towards the propeller. In outboard water, abrasive particles are present and it is advisable to filter this before it is pumped through your stern tube. Nonetheless, the materials of the more vulnerable parts of the seal have been optimised to be more wear resistant. High wear-resistant NBR lip seals run on a corrosion-resistant liner with a hardened surface, to prolong the average time between seal maintenance.

The seal is modified with a stainless steel fresh water tank to provide lubrication for the outermost lip seal. Via level switches on this tank, status monitoring of your lip seals is provided giving you an early warning of possible problems – before any real damage is done. We call this condition monitoring. It is also equipped with an inflatable safety seal, which can be activated in case in situ maintenance is due while afloat. During maintenance the seal can be manually adjusted radially for a perfect shaft-to-bore alignment, giving you a reliable sealing solution for years to come.
