Abstract (en)

[origin: WO2019038130A1] 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.
