e-GS SERIES

PUMPS

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.

Among the various products considered there are also some typologies of pumps with the characteristics defined by

the specific Regulation (EU) n. 547/2012 implementing the requirements of Directives EuP and ErP.

For vertical multi-stage pumps (MS-V for the Regulations), the efficiency evaluation refers to:

• just the pump and not the pump and motor assembly (electric or combustion);

• pumps with a nominal pressure PN not higher than 25 bar (2500 kPa);

• pumps designed to operate at a speed of 2900 min-

(for electric pumps this means 50 Hz 2-pole electric

motors);

• pumps with a maximum flow of 100 m

/h;

• 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).

The Regulation also establishes the following deadlines:

Regulation (EU) n. 547/2012 – Annex II – point 2 (Product information requirements)

1) Minimum efficiency index: see the MEI column in the tables in the “Hydraulic performance range” section.

2) “The benchmark for most efficient water pumps is MEI ≥ 0,70”.

3) Year of manufacture: from January 2013.

4) Manufacturer: Lowara srl Unipersonale - Reg. No. 03471820260 - Montecchio Maggiore, Vicenza, Italy.

5) Product type: see the PUMP TYPE column in the tables in the “Hydraulic performance range” section.

6) Hydraulic pump efficiency with trimmed impeller: not applicable to these products.

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/efficiencycharts or http://europump.net/uploads/Fingerprints.pdf

(refer to “Multistage Vertical 2900 rpm”).
