With the “Energy using Products” (EuP 2005/32/EC) and “Energy related Products” (ErP 2009/125/EC) directives,
the European Commission has established requirements for promoting the use of products with low power
consumption.
The Commission Regulation (EU) No 547/2012 has implemented two directives with regard to ecodesign
requirements for some types of clean water pumps placed on the market and put into service inside EU zone
as self-alone units or integrated in other products.
For end-suction close-coupled pumps (ESCC for the Regulation) and end-suction own-bearing pumps (ESOB for the
Regulation) the efficiency assessment refers to:
just the pump and not the pump and motor assembly (electric or combustion);
pumps with just one impeller;
pumps with a nominal pressure PN not higher than 16 bar (1600 kPa);
pumps with a minimum nominal flow not less than 6 m
3
/h;
pumps with a maximum nominal power at the shaft not higher than 150 kW;
pumps designed to operate at a speed of 2900 min-
1
(for electric pumps this means 50 Hz 2-pole electric
motors) and with a head not greater than 140 metres;
pumps designed to operate at a speed of 1450 min-
1
(for electric pumps this means 50 Hz 4-pole electric
motors) and with a head not greater than 90 metres;
use with clean water at a temperature ranging from -10°C to 120°C (the test is performed with cold water at a
temperature not higher than 40°C).
According to the definitions established in the Regulation NSCE and NSCS versions correspond to the “end-suction
close-coupled pump” while NSC, NSCF and NSCC versions correspond to the “end-suction own bearing pump”.
This regulation states that water pumps shall have a minimum index MEI coming from a dedicated formula which
considers hydraulic efficiency values at ‘best efficiency point’ (BEP), 75 % of the flow at BEP (Part load – PL) and 110
% of the flow at BEP (Over load – OL).
The Regulation also establishes the following deadlines.
NSC2 models are out of the scope of the Regulation.
Regulation (EU) n. 547/2012 – Annex II – point 2 (Product information requirements)
1) Minimum efficiency index: see MEI values in specific tables on following page.
2) “The benchmark for most efficient water pumps is MEI 0,70”.
3) Year of manufacture: 2014.
4) Manufacturer: Xylem Service Italia Srl - Reg. No 07520560967 - Montecchio Maggiore, Vicenza, Italy.
5) Product type: see the PUMP TYPE column in the tables in the Hydraulic performance section.
6) Hydraulic pump efficiency with trimmed impeller: see ηp and ØT columns in the tables in the Hydraulic
performance section.
7) Pump performance curves, including the performance curve: see the Operating Characteristics graphs in the
following pages.
8) “The efficiency of a pump with a trimmed impeller is usually lower than that of a pump with the full impeller
diameter. The trimming of the impeller will adapt the pump to a fixed duty point, leading to reduced energy
consumption. The minimum efficiency index (MEI) is based on the full impeller diameter”.
9) “The operation of this water pump with variable duty points may be more efficient and economic when
controlled, for example, by the use of a variable speed drive that matches the pump duty to the system”.
10) Information relevant for disassembly, recycling or disposal at end-of-life: observe the current laws and by-laws
governing sorted waste disposal. Consult the product operating manual.
11) “Designed for use below – 10 °C only”: note not applicable to these products.
12) “Designed for use above 120 °C only”: note not applicable to these products.
13) Specific instructions for pumps as per points 11 and 12: not applicable to these products.
14) “Information on benchmark efficiency is available at”: www.europump.org (Ecodesign section).
15) The benchmark efficiency graphs with MEI = 0.7 and MEI = 0.4 are available at www.europump.org,
Ecodesign,Efficiency charts (refer to “ESCC 1450 rpm”, “ESCC 2900 rpm”, “ESOB 1450 rpm”, “ESOB 2900 rpm”).
