A propellershaft is part of the ship’s shaft system and seals open or closed stern tube systems so that no water can penetrate and no lubricating oil can escape. Similar to a mechanical seal, it is virtually leak-free and leaves no oil or grease residues in the fairway. At the same time, penetration of dirty water into the bilge is prevented – thus eliminating costly disposal.

The ProfiSeal propellershaft has a shaft diameter of 20 to 200 millimetres and is available in both water- and oil-lubricated versions. The axial sealing concept prevents the shaft from running in, which is otherwise common with radial seals.

In addition to the propellershaft, we offer the Pneumostop unit, an inflatable standstill seal. This makes it possible to replace, repair or clean mechanical seals and propellershafts when the shaft is at a standstill without having to call in a shipyard.
