Pipe a product bypass flush from the pump discharge to the X-200 seal flush port, 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.
