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. 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.

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 pres-
sure does not exceed 100 psig
(7.0 kg/cm
