(EN) NON-METALLIC BRUSH SEAL
Abrégé
(EN)

A rotary machine comprises a housing, a rotor that is rotatably disposed within the housing and having an axis about which the rotor may spin, and a seal disposed upon the housing. The seal comprises a support disposed on the housing and a plurality of flexible non-metallic bristles that extend from the housing and engage the rotor, such that the seal provides a barrier to fluid flow between a first region located in a first axial direction from the seal and a second region located in an opposite axial direction from the first region. The first region is filled with a bearing liquid and the second region is filled with a process fluid.
