Abstract

Die Erfindung betrifft Vakuumpumpe (1) mit einem Gehäuse (6), einer Ansaugöffnung (5), einem schnell drehenden Rotor (12) und einem mit einem Gegenflansch (2; 2'; 2") verbindbaren Pumpenflansch (4; 4'; 4"), welcher am Gehäuse vorgesehen ist. Um die Sicherheit der Flanschverbindung in einem Fehlerfal zu erhöhen, wird vorgeschlagen, dass auf der dem Gehäuse abgewandten Seite des Pumpenflansches ein der Ansaugöffnung zugeordneter Kragen (40; 40'; 40") angeordnet ist.
