The authors put forth a procedure for evaluating the energy efficiency of pumping equipment powered by electricity and operating under variable load, as well as a procedure created according to the guidelines of the European Pump Manufacturers Association (ENPA) based on the energy efficiency index (EEI). The article presents the results of analysis of energy efficiency values calculated based on different methods and the inherent disadvantages of the mathematical model used to determine the EEI index.
