COMMISSION REGULATION (EU) No 547/2012

of 25 June 2012

implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for water pumps

(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 European 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 Ecodesign Consultation Forum,

Whereas:

| (1) | Under Directive 2009/125/EC, ecodesign requirements are to be set by the Commission for energy-related products representing significant volumes of sales and trade, having a significant environmental impact and presenting significant potential for improvement in terms of their environmental impact without entailing excessive costs. |
| --- | --- |

(1)

Under Directive 2009/125/EC, ecodesign requirements are to be set by the Commission for energy-related products representing significant volumes of sales and trade, having a significant environmental impact and presenting significant potential for improvement in terms of their environmental impact without entailing excessive costs.

| (2) | Article 16(2) of Directive 2009/125/EC provides that, in accordance 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 shall, as appropriate, introduce implementing measures for products used in electric motor systems, such as water pumps. |

Article 16(2) of Directive 2009/125/EC provides that, in accordance 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 shall, 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-efficient 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 (2). Consequently, the present Regulation only sets minimum requirements for the hydraulic performance of water pumps without the motor. |

The Commission has carried out a preparatory study to analyse the technical, environmental and economic aspects of water 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 consumption in the use phase is the most significant environmental aspect of all life-cycle phases, with their annual electricity consumption amounting to 109 TWh in 2005, corresponding to 50 Mt in CO2 emissions. In the absence of measures to limit 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. |

ANNEX III

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 reproducible methods, which take into account the generally recognised state of the 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 Annex 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 efficiency at best efficiency point (BEP) is as follows:
  Formula

Where,

x = ln (ns); y = ln (Q) and ln = natural logarithm and Q = flow in [m3/h]; ns = specific speed in [min–1]; C = value found in Table.

The value of C depends on the pump type and nominal speed, and also the MEI value.

Formula

Formula

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 number of stages within the product range is to be chosen for testing.

ANNEX IV

Verification procedure for market surveillance purposes

When performing the market surveillance checks referred to in Article 3(2) of Directive 2009/125/EC, the authorities of the Member States shall apply the following verification procedure for the requirements set out in Annex II.

| 1. | The authorities of the Member State shall test one single unit per model and provide the information about testing results to the authorities of the other Member States. |
| --- | --- |

1.

| 2. | The model shall be considered to comply with the provisions set out in this Regulation, if the hydraulic pump efficiency measured at each of the conditions BEP, PL and OL (ηΒΕΡ, ηΡL, ηΟL) does not vary below the values set out in Annex II by more than 5 %. |
| --- | --- |

2.

| 3. | If the result referred to in point 2 is not achieved, the market surveillance authority shall randomly test three additional units and provide the information about testing results to the authorities of the other Member States and to the European Commission. |
| --- | --- |

3.

| 4. | The model shall be considered to comply with the provisions set out in this Regulation, if the pump passes the following three separate tests, if the:
