Abstract

Pumpe, umfassend ein Aufnahmegehäuse (20), welches einen topfförmigen Aufnahmeraum (25) mit einer Stirnwand (20c) und einer Umfangswand (20d) bildet, einen Pumpeneinsatz (1), der in dem Aufnahmeraum (25) angeordnet ist, wobei der Pumpeneinsatz (1) aufweist:
- einen Rotor (4) und eine Pumpenwelle (10),
- ein erstes Gehäuseteil (2) und ein zweites Gehäuseteil (3), zwischen denen der Rotor (4) um eine Drehachse (D) und relativ zu dem ersten und zweiten Gehäuseteil (2, 3) drehbar angeordnet ist, wobei die Pumpenwelle (10) verdrehfest mit dem Rotor (4) verbunden und in dem ersten Gehäuseteil (2) und in einer sackförmigen Ausnehmung des zweiten Gehäuseteils (3) drehbar gelagert ist,
- einen Hubring (12), welcher den Rotor (4) umgibt und zwischen dem ersten Gehäuseteil (2) und dem zweiten Gehäuseteil (3) angeordnet ist,
wobei
zwischen dem Aufnahmegehäuse (20) und dem zweiten Gehäuseteil (3) eine zweite Dichtung (8), insbesondere ein Dichtring, angeordnet ist, welche einen ersten Druckraum (23b), der zwischen der Stirnwand (20c) und dem zweiten Gehäuseteil (3) gebildet ist, in Bezug auf einen Saugraum (24), der zwischen der Umfangswand (20d) und dem Hubring (12) gebildet ist, abdichtet und
zwischen dem ersten Gehäuseteil (2) und dem Aufnahmegehäuse (20), insbesondere der Umfangswand (20d) des Aufnahmegehäuses (20), eine erste Dichtung (7), die beispielsweise die Abdichtung des Saugraums (24) nach außen hin oder zur Öffnung des Aufnahmegehäuses (20) hin bewirkt, angeordnet ist, wobei der Saugraum (24) zwischen der ersten Dichtung (7) und der zweiten Dichtung (8) gebildet ist, und
zwischen dem zweiten Gehäuseteil (3) und der Stirnwand (20c) des Aufnahmegehäuses (20) ein Dichtelement (9) angeordnet ist, welches einen zweiten Druckraum (23c) ringförmig umgibt.
