Mechanical seals, also known as end seals, are primarily used for the sealing of rotating shafts in pumps, compressors, hydraulic drives and other similar equipment. The mechanical seal is a sealing device composed of a pair of planar friction pairs composed of a pair of moving rings and stationary rings.
The mechanical seal is a device for preventing fluid leakage by at least a pair of end faces perpendicular to the rotation axis under the action of the fluid pressure and the compensating mechanism elastic force (or magnetic force) and the cooperation of the auxiliary seals. The auxiliary seal of the compensation ring is a metal bellows called a bellows mechanical seal.
