FIELD: oil and gas producing industry. ^ SUBSTANCE: invention can be used for transportation of liquid in water supply systems and in systems pumping oil and gas emulsion from well to gathering station. Proposed pump has housing, impeller with swirl and centrifugal channels arranged at both sides from impeller, and guide vane assemblies with flow dividers. Drive shaft is provided with longitudinal channels communicating side centrifugal zones of impeller. Channels of swirl zone are separated from central and peripheral zones by rigid sealing rings installed in walls of guide vane assemblies and impeller at its both sides. Swirl channels are essentially recess with concave bottom made to arc and changing into straight-line plane at side on-coming the flow. ^ EFFECT: improved operation reliability and increased efficiency. ^ 6 dwg |
