Abstract

Die Erfindung betrifft eine Pumpe (1) zur Förderung eines Pumpfluids (2) in Form eines Mehrphasengemischs, wobei im Betriebszustand das unter einem Eingangsdruck an einer Niederdruckseite (LP) der Pumpe bereitgestellte Pumpfluid (2) mittels einem in einem Pumpenstator (3) um eine Drehachse (A) drehbar gelagerten Pumpenrotor (4) auf eine Hochdruckseite (HP) der Pumpe beförderbar ist, und eine Rotorwelle (5) derart in einer Wellendurchführung (6) angeordnet ist, dass zwischen der Rotorwelle (5) und der Wellendurchführung (6) in einem Ringspalt (21) ein Schmierfilm aus einem aus dem Pumpfluid (2) gebildeten Schmierfluid (200) ausbildbar ist, und an der Rotorwelle (5) eine Separationseinrichtung (7) vorgesehen ist, mit welcher im Betriebszustand zur Bereitstellung des Schmierfluids (200) am Ringspalt (21) eine vorgebbare Menge eines Inhaltsstoffs mittels einer Zentrifugalkraft aus dem Pumpfluid (2) separierbar ist, dadurch gekennzeichnet, dass eine Rezirkulationseinrichtung (8) vorgesehen ist, sodass ein Gas (201) mit Hilfe der Separationseinrichtung (7) rezirkulierbar ist.
