Industrial Mechanical seals are employed at component interfaces to prevent leakage, maintain pressure, and deflect contamination. Applied at both static and dynamic contacts, industrial seals. They are used to seal the rotational portion of the seal onto the shaft. The interaction between the static and rotating parts of the seal is the mechanical seal itself. Industrial Mechanical seals act as a way to keep fluid inside a container where a rotating shaft passes through a stationary housing, or sporadically where the housing spins around the shaft.
