Abstract: A pump assembly with at least one liquid space (32) in an interior. The liquid space (32) contains a liquid or is configured for receiving a liquid. A sensor (34, 42) is arranged in the liquid space (32), which sensor is configured to detect at least one material property of the liquid located in the liquid space (32). A filter element (44) is arranged in the interior of the liquid space (32) such that the filter element (44) shields the sensor (34, 42) with respect to the surrounding liquid space (32), the filter element (44) being permeable to the liquid. A method for controlling a pump assembly is also provided.
