Description: Plan 41 is recirculation from pump
discharge through a CYCLONE SEPARATOR,
sending clean flush through a seal flush cooler,
then into the seal chamber. Heavy particles are
sent back to pump suction.
Objective: Cool and clean process being sent to
the seal chamber, improving lubricity and
increasing the vapor margin in the seal chamber.
Advantages: Provides cooler and cleaner
flush to the seal. When used with a closeclearance
throat bushing, can raise the
pressure in the seal chamber while
preventing erosion to the seal from
