BS EN 17038-1:2019 Pumps. Methods of qualification and verification of the Energy Efficiency Index for rotodynamic pump units - General requirements and procedures for testing and calculation of Energy Efficiency Index (EEI)
1 Scope
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.
