must be operating properly to prevent excess heat generation, sparks, and premature
failure.
•
manual venting prior to operation. Failure to do so will result in excess heat generation and
seal failure.
NOTICE:
The mechanical seal must have an appropriate seal-flush system. Failure to do so will
result in excess heat generation and seal failure.
When to install
You may need to install auxiliary piping for bearing cooling, seal-chamber cover cooling,
mechanical seal flush, or other special features supplied with the pump. Consult the pump data
sheet for specific auxiliary piping recommendations.
Checklist
