This article describes the methodology for assessing the energy efficiency of pumping systems equipped with a variable electric drive and operating with variable load, which was elaborated by the authors of the article. The analysis of traditional methods of recalculating the characteristics of the efficiency of pumping units when changing the frequency of rotation of the impeller using the formulas of theories of hydrodynamic similarity of blade blowers is presented. It is shown that in the derivation of the similarity formulas assumptions were made, which were not fully confirmed later when testing operating pumps. An algorithm and a technique developed by the authors are presented that allow one to read the actual values of the efficiency from the pre-digitized universal characteristics of vane blowers The results of comparison of efficiency values calculated by different methods are presented.
