To obtain the desired sealing function and an adequate lifetime of the mechanical seal,the preconditions must be fulfilled within the permitted tolerances at any time:
- parallelism of the sealing surfaces
- perpendicularity of the seal faces to the rotation axis
- elastic contact of the sealing surfaces
- existence of a lubricating film between the two sealing surfaces
Usually the sealing capability of the mechanical seal against shaft or housing is obtained with the secondary seals, as O-rings, bellows or boots
In conjunction with the International Organization for Standardization (ISO) and their standards (ISO 3069), the German Industrial Standard (DIN) published proposals for standard mechanical seals with DIN EN 12756 (24960).
These proposals relate to the sealing rooms, main dimensions, designation and material codes.

What advantages do mechanical seals have compared to other seals?
The so-called stuffing box packing is the predecessor model of the mechanical seal. This product is a braided product. The system requires a lekage, it drips almost constantly, so there is immense fluid consumption. A mechanical seal, on the other hand, does not lose fluid and is lekage-free. An all-round reliable seal, for example, is thus given in any case. Chemical substances or dangerous vapours and smoke can therefore no longer escape.
