Hot Sell 504180969 Shaft seal, seal ring OE number by ALFA ROMEO, FIAT, IVECO, LANCIA A
The shaft seal is a sealing element which seals the rotating shaft, of a centrifugal pump where it passes through the non-rotating pump casing reducing fluidleakage to atmosphere or the entry of air from outside to a certain level, and keeps wear of the sealing faces as low as possible.During rotation, the shaft drags a thin film of lubricant past the wavy edge and into the seal-to-shaft interface, causing the seal to hydroplane. This hydroplaning action prevents the direct contact, dry rubbing wear, and high friction associated with conventional non-hydrodynamic seals.
