Vane-type rotary vacuum pump

The present disclosure relates to a vane-type rotary vacuum pump comprising a drive motor (1, 17) interacting with a vane-pump vacuum chamber (2), in which pump all the pump surfaces that are visible from the top are arranged in such a way that they have no elements likely to retain liquids or solid...

Zusammenfassung:	The present disclosure relates to a vane-type rotary vacuum pump comprising a drive motor (1, 17) interacting with a vane-pump vacuum chamber (2), in which pump all the pump surfaces that are visible from the top are arranged in such a way that they have no elements likely to retain liquids or solids. The drive motor (1) may in particular be an air-cooled asynchronous motor or a water-cooled asynchronous motor with a case that, with the cylinder (18), forms a space in which a cooling fluid can circulate.
