3.1 Pipe a product bypass flush from the pump discharge to the
X-200 seal flush port, a Figure 7. To maximize seal life,
Flowserve recommends that a product bypass flush be used
whenever possible with a X-200 seal installed in conventional
stuffing box. A bypass flush is not necessary when an enlarged
tapered or cylindrical seal chamber is used. If a bypass flush is
not used, plug the flush port a .
3.2 Taps b and c in the gland are buffer / barrier fluid inlet and
outlet ports. Which is the inlet port depends on the direction of
