摘要：
A sealing arrangement having inboard and outboard dynamic seals in a housing separated by a barrier fluid and having a sealed relationship with a relatively movable bearing-guided shaft. A bearing chamber having bearing lubricant exposed to the inboard dynamic seal. The inboard dynamic seal is a hydrodynamic seal having a hydrodynamic pumping action in response to relative rotation between the shaft and the inboard dynamic seal. The hydrodynamic pumping action forcing a film of the bearing lubricant between the inboard dynamic seal and the shaft. The hydrodynamic pumping-related leakage of the inboard dynamic seal being returned to the bearing chamber in which the shaft guidance bearings are located.
