Seal Flushing
To prevent the potential risk of hot surfaces on
the pump seals it is essential to apply additional
cooling and lubrication of the seal faces through
the use on an additional auxiliary support system
as described 3.11 SEALS AND FLUSHING.
In addition to the system requirements described
in 3.11 SEALS AND FLUSHING, controls must be
implemented to ensure the continuous and
uninterrupted operation of the flushing circuit
during pump operation.
It is essential to ensure that all the air/gas is
purged from the seal housings so that the seals
are fully immersed in the quench/barrier fluid.
