DEVICE FOR OIL TRANSFER FROM PIPELINES Russian patent published in 2014 - IPC F04D1/04 F04D9/04 F04D29/62 

FIELD: oil and gas industry.

SUBSTANCE: invention is related to the field of pump engineering and intended for transfer of oil and other liquids from pipelines during their repair when the maximum drainage of the pipeline is required. The device for oil transfer from pipelines contains a pump consisting of a case, a rotor with an impeller and the primary axial-vortex step set before the impeller inlet. The pump case is made as a plain pipe through which the device attachment fitting is moved freely thus providing installation of the pump up to the stop at the lower part of a pipe with any diameter. Entry to the primary axial-vortex step is radial. Before entry to the primary axial-vortex step there are radial vanes installed which pass into the fixed vanes of the axial-vortex step.

EFFECT: invention is oriented to manufacturing of a universal device for oil transfer from pipelines of different diameter that ensures minimum residual level.
