Abstract (en)

The centrifugal pump has an impeller that is rotatably mounted on a shaft, which is sealed off by seal (11) to a surrounding housing. The seal is opened towards a container (12) for the collection of the fluid, and is configured to detect fluid in or out of the container. The container is annular and is configured to surround the shaft. A sensor (20) configured for detecting the flow rate of drops. A discharge opening is followed by the tubes (21,22) formed by the sensor whose other end is open to the outside or to a discharge line.
