The AxiSeal is an axial seal. A totally different way of sealing from a radial seal, like the conventional stuffingbox or lip-type seal. With a radial seal the sealing rings run directly on the propeller shaft. This often causes wear of the sealing rings and the propeller shaft within a short period. With leakage as result. The AxiSeal seals axial (parallel to the shaft direction). The together with the propeller shaft rotating, self centring Silicon Carbide (SiC) rotary face runs against a Silicon Carbide (SiC) stationary seat. By "lapping" both of these surfaces the right way, a lubricating film is built up during the rotating of the propeller shaft. This results in a very low friction coefficient. This guarantees a long life.
Seals have been developed to operate on propeller shafts of small, medium and large size boats where a high level of reliability is required.
The special design allows large axial displacement and the use of suitable material guarantees as well as high resistance to corrosion and high mechanical resistance to withstand stresses produced by vibrations.
The installation of mechanical seals in this particular field has solved problems such as corrosion during long periods of inactivity and shaft damage caused by traditional stuffing boxes. Power absorption is considerably reduced as well.
