# 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), Article 2: Definitions

Extent: E+W+S+N.I.

The definitions set out in the Ecodesign for Energy-Related Products Regulations 2010 apply; and for any term that is not defined in those Regulations, the definitions set out in 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, as it had effect immediately before IP completion day, apply. The following definitions also apply—
(1)‘water pump’ is the hydraulic part of a device that moves clean water by physical or mechanical action and is of one of the following designs:
End suction own bearing (ESOB),
End suction close coupled (ESCC),
End suction close coupled inline (ESCCi),
Vertical multistage (MS-V),
Submersible multistage (MSS);
(2)‘End suction water pump’ means a glanded single stage end suction rotodynamic water pump designed for pressures up to 16 bar, with a specific speed ns between 6 and 80 rpm, a minimum rated flow of 6 m3/h (1,667·10–3 m3/s), a maximum shaft power of 150 kW, a maximum head of 90 m at nominal speed of 1 450 rpm and a maximum head of 140 m at nominal speed of 2 900 rpm;
(3)‘Rated flow’ means the head and flow that the manufacturer will guarantee under normal operating conditions;
(4)‘Glanded’ means sealed shaft connection between the impeller in the pump body and the motor. The driving motor component remains dry;
(5)‘End suction own bearing water pump’ (ESOB) is an end suction water pump with own bearings;
(6)‘End suction close coupled water pump’ (ESCC) is an end suction water pump of which the motor shaft is extended to become also the pump shaft;
(7)‘End suction close coupled inline water pump’ (ESCCi) means a water pump of which the water inlet of the pump is on the same axis as the water outlet of the pump;
(8)‘Vertical multistage water pump’ (MS-V) means a glanded multi stage (i > 1) rotodynamic water pump in which the impellers are assembled on a vertical rotating shaft, which is designed for pressures up to 25 bar, with a nominal speed of 2 900 rpm and a maximum flow of 100 m3/h (27,78·10–3 m3/s);
(9)‘Submersible multistage water pump’ (MSS) means a multi stage (i > 1) rotodynamic water pump with a nominal outer diameter of 4″ (10,16 cm) or 6″ (15,24 cm) designed to be operated in a borehole at nominal speed of 2 900 rpm, at operating temperatures within a range of 0 °C and 90 °C;
(10)‘rotodynamic water pump’ means a water pump that moves clean water by means of hydrodynamic forces;
(11)‘displacement water pump’ means a water pump that moves clean water by enclosing a volume of clean water and forcing this volume to the outlet of the pump;
(12)‘self-priming water pump’ means a water pump that moves clean water and which can start and/or operate also when only partly filled with water;
(13)‘clean water’ means water with a maximum non-absorbent free solid content of 0,25 kg/m3, and with a maximum dissolved solid content of 50 kg/m3, provided that the total gas content of the water does not exceed the saturation volume. Any additives that are needed to avoid water freezing down to – 10 °C shall not be taken into account.
The definitions for the purpose of Annexes II to V are set out in Annex I.
