【 摘 要 】

A comparative analysis of VS6 pump type in the range of specific speed nq= 25...55 was carried out basing on information about analogous pumps produced by the world's leading manufacturers. The focus was made on mass-dimensional characteristics of the pump stages. It was found that rational design of a diffuser with radial vanes provides lower material consumption at similar hydraulic characteristics compared to using a semi-axial vanes diffuser in the stage.
