Abstract: A coolant pump with an integrated shaft bearing (ISB) assembly is provided. The ISB has a bearing housing, and at least one bearing located therein supports a shaft. A bearing seal is connected to the bearing housing at a first axial end and contacts the shaft, and a vent cover is also located at the first axial end to define a vent space between it and the bearing seal. A seal assembly is located between the shaft and the vent cover. A vent insert is located in the vent space and connected for rotation with the shaft. Venting air enters via a vent space inlet connected to the vent space, and is exhausted by a vent space outlet. A generally annular collection cavity is located inside the vent space and connected to the vent space outlet. This allows for active purging of condensate or coolant leakage to protect the bearing.
