API Plan 54 Barrier Fluid Pressurized by External System
API Plan 54 is a custom engineered system that delivers a pressurized barrier fluid to the seal chamber. The barrier liquid is circulated to and from the seal chamber via a pump located on an external reservoir. This fluid is maintained at a pressure greater than that found in the seal chamber. A Plan 54 can contain filters, coolers, and other components that are selected according to the specific parameters of the application.
