The article discusses the effectiveness of dumping devices of sectional centrifugal pumps. A quantitative estimation of the volume and mechanical losses was assessed, as well as volumetric and mechanical efficiency, depending on the width of the gap in the handling device of the sectional pump TsNSG 850-240 ... 960. The activities to improve the performance of these devices were suggested.
