Solution-focused

Back in the late 1970s, the development of custom-made propeller shafts began in Werkendam. Even before the environment started to play a significant role in shipping, De Waal was already experimenting and producing propeller shaft seals that were affordable and effective.

Sophisticated dimensions

Our great strength is that systems are made to fit any existing propeller shaft diameter. Unique in the market! For new-build ships, we use our own range of optimum dimensions. We have a solution for everything.

A completely closed propeller shaft system or just a single seal on the inside or outside? Anything is possible. For oil, grease or water lubrication. The Stuwa© seal can be used for any vessel.

Fitting a Stuwa outer seal.

These days, all existing barges are required by the government to be 'clean' in terms of propeller shafts. Zero leakage' is the standard. All our seals are certified by Green Award; the environmental seal of approval for the shipping industry. You will also receive attractive benefits if several parts of your vessel are certified.
