The advantage of a mechanical
seal is the very low leakage (some leakage is necessary for lubrication and
cooling). The leakage is so small that they are therefore also called
leak-free. If media are pumped, which do not evaporate quickly, you can clearly
see that a mechanical seal is not leak-proof. With oil, for example, the space
around the seal will become completely greasy.
A mechanical seal (mechanical seal) consists of a number of
