Abstract: A seal assembly for a turbomachine. The turbomachine includes a rotating shaft extending along a centerline and a fixed housing positioned exterior to the rotating shaft in a radial direction relative to the centerline. The seal assembly includes a sump housing at least partially defining a bearing compartment for holding a cooling lubricant. The seal assembly further includes a bearing supporting the rotating shaft. In addition, the seal assembly also includes a sump seal at least partially defining the bearing compartment. A pressurized housing of the seal assembly is positioned exterior to the sump housing and defines a pressurized compartment to at least partially enclose the sump housing. Further, a non-contacting carbon seal is positioned between the rotating shaft and the fixed housing to at least partially define the pressurized compartment to enclose the sump housing.
