AXISEALS

The AxiSeal® is applied in water lubricated propeller shaft systems. Blokland Non Ferro will be delighted to give its recommendations about the conversion of a grease lubricated system into a water lubricated one.

How does the AxiSeal® work?

The AxiSeal® is a truly unique mechanical seal, a totally different way of sealing in comparison to a radial seal, such as the conventional stuffing box or lip-type seal. In the case of a radial seal the sealing rings run directly onto the propeller shaft surface. Inevitably, this causes wear of the sealing rings and the propeller shaft within a relatively short period of time, leakage being the unwanted result.

The AxiSeal® performs its task in the axial mode (parallel with the shaft’s centerline). The Silicon Carbide (SiC) rotary face runs together with the propeller shaft, against a Silicon Carbide (SiC) stationary seat. The minuscule coefficient of friction, combined with a lubricating water film results in a very long life span of the AxiSeal® sealing system.
