Damage to the pump set!
▷
Never operate the pump set without liquid fill.
▷ Never close the shut-off element in the suction line and/or supply line during
pump operation.
CAUTION
Impermissibly high temperature of fluid handled
Damage to the pump!
▷ Prolonged operation against a closed shut-off element is not permitted
(heating up of the fluid).
▷ Observe the temperature limits in the data sheet and in the section on
operating limits.
While the pump is in operation, observe and check the following:
▪ If activated, check the functional check run.
▪ Measure the actual start-up pressure and stop pressure of the pump sets with a
pressure gauge. Compare the values with the specifications on the name plate.
▪ Compare the pre-charge pressure of the accumulator with the recommended
data. (

▪ Check the rolling element bearings for running noises.
Vibrations, noise and an increase in current input occurring during unchanged
operating conditions indicate wear.
