PL 54/55 lubrication systems provide a positive flow and pressure of pressurized or unpressurized barrier/buffer fluid to dual seals. This seal support system type is typically preferred where flow and heat removal capacity exceeds that of API Plan 52 or 53 seal support systems.
Note: API Plan 54 and 55 designations apply to the barrier/buffer fluid circuit and not to the external system.
