(Text with EEA relevance) 
THE EUROPEAN COMMISSION, 
Having regard to the Treaty on the Functioning of the European Union, Having regard to Directive 2009/125/EC of the Eu ropean Parliament and of the Council of 21 
October 2009 establishing a framework for the setting of ecodesign requirements for energy-
related products
1, and in particular Article 15(1) thereof,  
After consulting the Ecodes ign Consultation Forum, 
Whereas: (1) Under Directive 2009/125/EC, ecodesign re quirements are to be set by the 
Commission for energy-related  products representing signi ficant volumes of sales and 
trade, having a significant environmental impact and presenting significant potential 
for improvement in terms of their environm ental impact without entailing excessive 
costs. 
(2) Article 16(2) of Directive 2009/125/EC provides that, in acc ordance with the procedure 
referred to in Article 19(3) and the criteria set out in Article 15(2) , and after consulting 
the Consultation Forum, the Commission sha ll, as appropriate, introduce implementing 
measures for products used in electric motor systems,such as water pumps.  
(3) Water pumps forming parts of electric motor systems are essential in various pumping 
processes. There is a total cost-effective potential for improving the energy efficiency 
of these pumping systems by approximately 20% to 30%. Even though the main savings can be achieved by motors, one of the factors contributing to such 
improvements is the use of energy-efficien t pumps. Consequently, water pumps are a 
priority product for which ecodesign requirements should be established. 
(4) Electric motor systems include a number of energy-related products, such as motors, 
drives, pumps or fans. Water pumps are one  of these products. Minimum requirements 
are established for motors in a separate  measure, Commission Regulation (EC) No 
640/2009/EC
2. Consequently, the present Regulation only sets minimum requirements 
for the hydraulic performance of water pumps. 
(5) Many pumps are integrated in  other products without bei ng separately placed on the 
market. To achieve the full cost-effectiv e energy-saving potential, water pumps 
integrated in other products s hould also be subject to the pr ovisions of th is Regulation.

EN 2   EN (6) The Commission has carried out a prepar atory study to analyse the technical, 
environmental and economic aspects of wa ter pumps. The study has been developed 
together with stakeholders and interested parties from the Union and third countries, 
and the results have been made publicly available. 
(7) The preparatory study shows that water pumps are placed on the European Union 
market in large quantities. Their energy c onsumption in the use phase is the most 
significant environmental aspect  of all life-cycle phases, w ith their annual electricity 
consumption amounting to 109 TWh in  2005, corresponding to 50 Mt in CO 2 
emissions. In the absence of measures to li mit this consumption, it is predicted that 
energy consumption will increase to 136 TWh in 2020. It has been concluded that use-
phase electricity consumption can be improved significantly.   
(8) The preparatory study shows that electricity consumption in the use phase is the only 
significant ecodesign parameter related to produc t design as referred to  in Annex I, Part 
1, to Directive 2009/125/EC. 
(9) Improvements in electricity consumption in  the use phase of water pumps should be 
achieved by applying existing non-proprieta ry cost-effective technologies that can 
reduce the total combined costs of purchase and operation. 
(10) Ecodesign requirements should harmonise power consumption requirements for water 
pumps throughout the European Union, thus contributing to the functioning of the 
internal market and to the improvement of  the environmental performance of these 
products. 
(11) An appropriate timeframe should be provide d for manufacturers to  redesign products. 
The timeframe should be such as to avoi d negative impacts on th e functionalities of 
water pumps and to take into account cost impacts for manufacturers, in particular 
small and medium-sized enterprises, while ensuring timely achievement of the objectives of this Regulation. 
(12) Power consumption should be determined using reliable, accura te and reproducible 
measurement methods, which take into ac count the recognised state-of-the-art 
including, where available, harmonise d standards adopted by the European 
standardisation bodies, as liste d in Annex I to Directive 98/34/EC of the European 
Parliament and of the Council of 22 J une 1998 laying down a procedure for the 
provision of information in the field of tec hnical standards and regul ations and of rules 
on Information Society services
3. 
(13) This Regulation should increase the market penetration of technologies that improve 
the life-cycle environmental im pact of water pumps, leadi ng to estimated electricity 
savings of 3.3 TWh by 2020, compared to the situation where no measures are taken. 
(14) In accordance with Article 8(2) of Directive 2009/125/EC, this Regulation should 
specify the applicable conformity assessment procedures. 
(15) In order to facilitate compliance checks, manufacturers should provide information in 
the technical documentation referred to in Annexes IV and V to Directive 2009/125/EC. 
(16) In order to further limit the environmen tal impact of water pumps, manufacturers 
should provide relevant information on disasse mbly, recycling or disposal at end-of-
life.

consumption.

Measurements and calculations  
For the purposes of compliance and verification of compliance with the requirements of this 
Regulation, measurements and calculations shall be made using harmonised standards the 
reference numbers of which have been published in the Official Journal of European Union , 
or using other reliable, accurate and reprodu cible methods, which take into account the 
generally recognised state of th e art, and produce results deemed  to be of low uncertainty. 
They shall fulfil all of the following technical parameters. 
The hydraulic pump efficiency, as defined in A nnex I, is measured at the head and flow 
corresponding to the best efficiency point (BEP ), part load (PL) and over load (OL) for full 
impeller diameter with clean cold water.  
The formula for calculating the required minimum ef ficiency at best efficiency point (BEP) is 
as follows:   
(ηBEP) min requ  = 88.59 x + 13.46 y -11.48 x2 – 0.85 y2 – 0.38 x y — C Pump Type,rpm 
Where, 
x = ln (n s); y = ln (Q) and ln = natural logarithm; n s = specific speed; C = value found 
in Table 1. 
The value of C depends on the pump type and speed, and also the MEI value.

The requirements forpart load (P L) and over load (OL) conditions  are set at slightly lower 
values than those for  100% flow ( ηBEP). 
 
 
All efficiencies are based on full (untrimmed) impeller. Vertical multistage water pumps are 
to be tested with a 3 stage (i=3) version. Submersible multistage water pumps are to be tested with a 9 stage (i=9) version. If this number of stages is not offered within the specific product 
range the next higher numb er of stages within the product range is to be chosen for testing.
