Designing pumps, compressors and other equipment, the aim is to prevent leakage into that can emerge at any point by liquids or gases. To solve this problem very often are used mechanical seals. 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).
