During flushing, make sure to rotate the shaft slowly by hand.
2.
Flush the bearing housing with the proper lubricating oil to ensure oil quality after cleaning.

5.5 Shaft sealing with a mechanical seal
Precautions
WARNING:
The mechanical seal used in an Ex-classified environment must be properly certified.
NOTICE:
•
The mechanical seal must have an appropriate seal-flush system. Failure to
do so will result in excess heat generation and seal failure.
•
Cooling systems such as those for bearing lubrication and mechanical-seal
systems must be operating properly to prevent excess heat generation, sparks, and pre-
mature failure.
