DIN EN 17038-2:2017-02

This European Standard is the second part of a series of standards describing a methodology to evaluate energy efficiency performance of pump units, comprising the pump, the motor with or without frequency converter, based on a non-dimensional numerical value called Energy Efficiency Index (EEI) - This European standard specifies methods and procedures for testing, calculating and determining the Energy Efficiency Index (EEI) of rotodynamic glanded single pump units for pumping clean water, including where integrated in other products.
