Sealing components include details used to manufacture, repair and replace mechanical seals such as seal faces, bellows, springs, O-rings and metal parts. The quality of each part directly affects the sealing and lifespan of the entire seal.
The seal face pair creates the main liquid film seal. Gaskets seal the auxiliary gaps between the seal and the shaft and pump body. Springs or bellows maintain stable pressure when the shaft moves or the seal face wears. Just one incompatible part can cause the entire seal to fail prematurely.
Seal faces require very high flatness, usually measured in a few light bands, and uniform surface roughness. Gaskets need correct size, hardness and material. The tolerance of metal parts affects the concentricity and stability during rotation.
Compare the seal code, size and original material with the drawing. Choose materials based on the medium, temperature and pressure, not just size. For important seals, use components from the manufacturer or components with clear quality certification.
Maintenance and repair of seals in factories, mechanical workshops and pump service units.
