Make sure that a leakage does not cause
damage to the equipment.
The seal faces are lubricated by the pumped liquid,
meaning that there may be a certain amount of
leakage from the shaft seal.
When you start the pump for the first time, or when
you install a new shaft seal, a certain run-in period is
required before the leakage is reduced to an
acceptable level. The time required for this depends
on the operating conditions, that is every time the
operating conditions change, a new run-in period will
be started.
Under normal conditions, the leaking liquid will
evaporate. As a result, no leakage will be detected.
