EN 17038-1:2019 Pumps - Methods of qualification and verification of the Energy Efficiency Index for rotodynamic pump units - Part 1: General requirements and procedures for testing and calculation of Energy Efficiency Index (EEI)
This document describes a methodology to evaluate energy efficiency performance of pump units based on a non-dimensional numerical value called Energy Efficiency Index (EEI). This document covers pump units consisting of: ?? one single or several rotodynamic water pump(s)@ including where integrated in other products@ and driven by a motor system@ consisting of an electrical motor@ and either: ?? a terminal box which only enables to operate the pump unit at constant motor stator frequency and thereby (nearly) constant rotational speed@ or ?? a CDM (Complete Drive Module) which enables to operate the pump unit at variable rotational speed depending on a varying demand of flow rate and/or discharge or differential pressure. NOTE A CDM is also often called VSD (Variable Speed Drive). Pump units as defined above are treated as extended products in respect to their energy efficiency.
