Worn shaft seal Check flushing / sealing liquid pressure
clean sealing liquid line, possibly introduce
sealing liquid from an external source or
increase pressure
Replace shaft seal

Unfavourable flow to suc -
tion nozzle of pump
Alter piping
If necessary, alter intake pipe if resistances
are too high
Check whether pipe routing results in twi-
sted or irregular flow (e.g. downstream of
an elbow) and correct, if necessary.
