Reliability (Mechanical Seals Failure Modes 1): Opening of the sealing gap: Some suspensions and solutions tend to cause build-up of scattered deposits on the seal faces. As the deposits only cover part of the seal faces, the sealing gap opens correspondingly. The result is a leaking shaft seal. The leakage is small at the beginning, accelerating as more liquid passes the sealing gap.

Deposits on carbon graphite seal face; The settlement accelerates, because the
temperature is higher on the surface of the already anchored deposits.
