Pumps - Methods of qualification of the Energy Efficiency Index for rotordynamic pump units - Part 3: Testing and calculation of energy efficiency index (EEI) of booster sets
This document specifies methods and procedures for testing, calculating and determining the energy efficiency index (EEI) of booster sets.
A booster set is either a single pump unit or an assembly of pump units connected in parallel with a maximum hydraulic power of 150 kW, a minimum rated flow of 6 m3/h (0,001667 m3/s), operated with backflow prevention and additional components influencing hydraulic performance and with components necessary to control pressure or provide flow in open loops inside buildings and which is placed on the market and/or put into service as one single product and its intended use is to pump clean water and does not have a self-priming functionality.
A booster set with a rated flow below 6 m3/h is composed using pumps that comply with EN 17038-2.

European foreword
This document (prEN 17038-3:2024) has been prepared by Technical Committee CEN/TC 197 “Pumps”,
the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
Introduction
This document is the third part of a series of standards describing a methodology to evaluate energy
efficiency performance of booster sets, comprising one or more pump(s), the motor(s) with or without
frequency converter, and additional components influencing hydraulic performance. It is based on a non-
dimensional numerical value called energy efficiency index (EEI). An EEI allows the comparison of
different configurations with one common indicator. Physical influences such as number and size of the
incorporated pump(s), pump unit part-load operation, motor-efficiency characteristic and frequency
converter influence are implemented into this metric.
Specific requirements for testing and a calculation method for EEI, the so called semi-analytical model
(SAM) of a complete booster set, a specific flow-time profile and a reference control curve are given in
this part of the series of standard.
EEI is an index to rate booster sets according to their energy efficiency but does not replace the need to
do a life-time cost analysis regarding energy consumption over the lifetime of the booster set.
1 Scope
This document specifies methods and procedures for testing, calculating and determining the energy
efficiency index (EEI) of booster sets.
A booster set is either a single pump unit or an assembly of pump units connected in parallel with a
3 3
maximum hydraulic power of 150 kW, a minimum rated flow of 6 m /h (0,001667 m /s), operated with
backflow prevention and additional components influencing hydraulic performance and with
components necessary to control pressure or provide flow in open loops inside buildings and which is
placed on the market and/or put into service as one single product and its intended use is to pump clean
water and does not have a self-priming functionality.
A booster set with a rated flow below 6 m /h is composed using pumps that comply with EN 17038-2.
