Our water-lubricated propeller shaft seal is a cost-effective and environmentally friendly solution that meets all technical needs for a modern mechanical marine seal. These include, among other things, a modular design, ease of installation, low maintenance requirements and no adjustment work.
Propeller shaft seals use the same function principle as mechanical seals. Therefore, they are virtually leakage free and leave no oil or grease residue in the waterway. The prevention of dirty water entry in the bilge is another feature of the STB propeller shaft seal, so there is no need for a cost and work intensive removal and disposal.
Optionally, we offer the enhancement with a Pneumostop. The Pneumostop enables the possibility to replace, repair or clean the mechanical seal and other components up to the Pneumostop on a standing shaft, without the need to go for a dockyard.
