Condition
Dry running/insufficient lubrication P << P0
Closed pressure slider P ≤ P0
Insufficient delivery rate P ≤ P
min
Pumping break due to gas P << P0
Pumping break due to cavitation
(only in the case of complete cavitation) P << P0
Risk of cavitation due to excessive pumping
rate (Pmax must be defined) P > P
max
Plain bearing damage P > P
max
Tank emptied P << P0
Coupling break P >> P
max
ATTENTION
When external or internal medium is used for flushing,
dry running or insufficient lubrication of the plain
bearings in the pump cannot be detected.
