Abstract

L'invention concerne une pompe axiale duale comportant au moins un étage de pompage (1) pourvu d'un dispositif de pompage (2) tournant à l'intérieur d'un carter fixe (12). Le dispositif de pompage (2) comprend des canaux fermés (8) tournants constitués par l'ensemble solidaire ; le rotor (3), les pales axiales (5,6,7) et le cylindre extérieur (4). Ainsi, la pompe axiale duale est dédiée au transport des mélanges fluides constitués de liquides plus ou moins visqueux, de gaz et une proportion de particules solides. Pour ce faire, le dispositif de pompage (2) tournant assure un écoulement confiné dans les canaux fermés (8) étanches, constituant ainsi une protection du contact entre la partie tournante (2) et le casing fixe (12). Aussi, les pales axiales (5,6,7) ont une configuration spécifique, adaptée au pompage des mélanges fluides. L'architecture de la pompe axiale duale permet l'augmentation significative de la fiabilité et des performances hydrauliques du transport des mélanges fluides complexes.
