Pumps - Methods of qualification and verification of the Energy Efficiency Index for rotodynamic pumps units - Part 1: General requirements and procedures for testing and calculation of Energy Efficiency Index (EEI)

Scope

This European standard 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.
