In Piping Plan 53B, there is an external barrier fluid system pressurized by a bladder accumulator supplying clean liquid to the barrier fluid seal chamber. The accumulator and barrier liquid are maintained at a pressure greater than seal chamber pressure. [API 682; G.19]. The pressure is maintained in the system by a bladder-type accumulator. The bladder prevents contact between the pressurized gas and the barrier fluid.
