6.2
Periodic maintenance
DANGER: Excessive temperatures due to friction
Regularly check the coupling protection and other covers of rotating parts for deformation and
enough clearance from the rotating parts themselves.
CAUTION: Excessive unit vibrations due to mechanical or installation failure
Check the vibrations of the pump and the motor at regular intervals or install a vibration
monitoring system.
DANGER: Risk of burns with hot and toxic fluid due to incorrectly serviced shaft seal
Regularly service the shaft seal.
CAUTION: Excessive temperatures due to bearings running hot or defective bearing seals
Regularly check the lubricant level and the bearing rolling elements for running noises.
DANGER: Leakage of hot and/or toxic fluid due to
i
ncorrectly serviced barrier fluid system
Regularly service the barrier fluid system and monitor the barrier fluid pressure.
Identify the lubrication type for the unit bearings by reading the last letter of the identification
code:
