gauge).
▷
Clean filter at appropriate intervals.
7.2.2.4 Checking the bearing seals
DANGER
Excessive temperatures caused by mechanical contact
Risk of explosion!
Damage to the pump set!
▷
Check correct seating of axial sealing rings mounted on the shaft.
Only gentle contact of the sealing lip shall be established.
7.2.3 Lubrication and lubricant change of rolling element bearings
DANGER
Excessive temperatures as a result of bearings running hot or defective bearing seals
Explosion hazard!
Fire hazard!
Damage to the pump set!
▷
Regularly check the condition of the lubricant.
7.2.3.1 Grease lubrication
The bearings are supplied packed with high-quality lithium-soap grease.
7.2.3.1.1 Intervals
Under normal conditions the grease-lubricated bearings will run for 15,000 operating
hours or 2 years. Under unfavourable operating conditions (e.g. high room
temperature, high atmospheric humidity, dust-laden air, aggressive industrial
atmosphere etc.), check the bearings earlier and clean and relubricate them, if
required.
