FIELD: transportation.
SUBSTANCE: device relates to pipeline transport. Proposed device comprises funnel located at pump outlet and extending from pump with angle of not more than α≤20°, changing into pipeline part with inner diameter making laminar fluid flow. If the hydrostatic pressure decreases over the pipeline length in 2 or more times, the inner diameter is reduced with a bell with an angle of not more than 20° to average values for similar pipelines. Liquid flow swirling facility is installed from inside the converging funnel and in the places with the highest head losses.
EFFECT: reduced losses of liquid head in the pipeline.
