Reliability (Mechanical Seals Failure Modes 1): Noise: When lubrication is poor or totally absent, shaft seals with seal rings made of hard materials tend to generate a loud noise. Depending on the seal design, the hard materials used and the system, the noise can be at a constant level of intensity and frequency or be more random.

Martin Mc Neill · Accepted Answer

When noise is generated from the mechanical shaft seal, some parts of the seal vibrate. This may reduce the life of the seal. Metal bellows seals in particular have a tendency to fatigue on account of vibrations.
