Precautions
CAUTION:
• Risk of heat generation, seal failure, and possible physical injury. Sealing systems that
are not self-purging or self-venting, such as plan 23, require manual venting prior to
operation.
• Running a mechanical seal dry, even for a few seconds, can cause seal failure and physi-
cal injury. Never operate the pump without liquid supplied to the mechanical seal.
NOTICE:
Auxiliary cooling and flush systems must be operating properly to prevent excess heat genera-
tion, sparks, and/or premature failure. Ensure auxiliary piping is installed as specified on the
pump data sheet prior to startup.
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
Check that the minimum flow for each
component is 4 lpm | 1 gpm.
Check that the cooling water pressure
does not exceed 7.0 kg/cm
