A pump rotor (11) contains a transponder (14) that can be read out by a reader (12) of a pump stator (10). The pump rotor (11) also contains sensors (26) for determining operating data (BD), and a memory (27). The memory (27) stores either the history of the measured operating data (BD) or a service life characteristic (LDK). In this way, the rate of wear of the respective rotor is determined and stored in the rotor, and the rotor therefore contains all of the information relating to maintenance. The rotor-related information remains in the rotor even if the rotor is used in another vacuum pump. |
