Precautions
WARNING:
• Cooling systems such as those for bearing lubrication and mechanical-seal systems must be operating
properly to prevent excess heat generation, sparks, and premature failure.
• Sealing systems that are not self-purging or self-venting, such as plan 23, require 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. Otherwise, excess heat generation and
seal failure can occur.
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
Check Explanation/
comment
Checked
Check that the minimum flow for each component is 1 gpm (4 lpm).
If the bearing and seal chamber cover cooling are provided, then the
auxiliary piping must flow at 2 gpm (8 lpm).
–
Check that the cooling water pressure does not exceed 100 psig (7.0 kg/
cm 2 ).

Final piping checklist
Check Explanation/comment Checked
Check that the shaft rotates smoothly. Rotate the shaft by hand. Make sure there is no
rubbing that can lead to excess heat generation or
sparks.
Re-check the alignment to make sure that
pipe strain has not caused any
misalignment.
If pipe strain exists, then correct the piping.
