Title (EN) PIPE AXIAL PUMP
(FR) POMPE AXIALE À TUYAU
(DE) ROHR-AXIALPUMPE
Abstract:
(EN) The invention relates to a pipe axial pump for pumping a liquid, wherein the motor (4) of the pump is arranged such that the liquid to be pumped flows around the motor and therefore no elaborate rotary leadthroughs of the pump shaft through the pipe system are needed. Furthermore, the bearings (61, 62) of the motor are lubricated by the liquid to be pumped, thereby avoiding risky oil lubrication. As a result, the pipe axial pump is suitable for use in drinking water pipelines.
(FR) L'invention concerne une pompe axiale à tuyau destinée à pomper un liquide, le moteur (4) de la pompe étant agencé de sorte à être entouré du liquide à pomper, de sorte qu'il ne soit pas nécessaire de recourir à des passages tournants complexes de l'arbre de pompe à travers le système tubulaire. En outre, les paliers (61, 62) du moteur sont lubrifiés par le liquide à pomper de sorte à éviter ainsi une lubrification à l'huile risquée. Ladite pompe axiale à tube se prête par conséquent à une utilisation dans des conduites d'eau potable.
(DE) Rohr-Axialpumpe zum Pumpen einer Flüssigkeit, wobei der Motor (4) der Pumpe von der zu pumpenden Flüssigkeit umströmt angeordnet ist, so dass keine aufwändigen Drehdurchführungen der Pumpenwelle durch das Rohrsystem notwendig sind. Ferner werden die Lager (61, 62) des Motors durch die zu pumpende Flüssigkeit geschmiert, sodass eine riskante Ölschmierung unterbleiben kann. Dadurch ist die Rohr-Axialpumpe für den Einsatz in Trinkwasserleitungen geeignet.
