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.

The invention relates to a vacuum pump (1) comprising a housing (6), a suction opening (5), a rapidly rotating rotor (12) and a pump flange (4, 4 ', 4') which can be connected to a counterflange (2; 2 ', 2 ") "), which is provided on the housing. In order to increase the safety of the flange connection in the event of a fault, it is proposed that a collar (40, 40 ', 40 ") assigned to the suction opening be arranged on the side of the pump flange facing away from the housing.
