A whisper is enough for those who want to hear (Farid Farjad)
Working equipment always whispers. Hearing the whisper before it turns into a scream is positive for taking action before the failure grows and damages shaft and casing. Although bearing failure signals may seem like this pump can be followed more and then taken into maintenance, it showed that the action taken was correct because the sound of the equipment started to change.
