Abstract
An inter-fluid brush seal assembly and associated method are provided. The seal assembly defines a gas passage for supplying gas to interfaces with a rotatable member. At least one of the interfaces is defined by a brush seal, and the flow of the gas through the interfaces can prevent the flow of fluid through the assembly, thereby sealing the assembly and preventing the fluid from passing therethrough. The gas and the fluid can be drained from the assembly through one or more drains.
