About Designing the Flow Part of a Multi-Stage Pump with a Minimum Radial Dimensions

There are the aspects of the issue to reduce the possibility of specific quantity of metal of flow of multi-stage pump in terms of reducing the radial dimensions while maintaining a high level of energy performance. One solution to this problem is to use two-row impellers. However, designing a two-row system blade and prediction of its characteristics is associated with a number of issues that are currently in the research involving the use of computer modeling of fluid flow in the flow of the pump.
