2.6 Ecodesign Minimum Efficiency Requirements Water Pumps
• Directive 2005/32/EC of the European Parliament and of the Council;
• Commission regulation (EU) No 547/2012 Implementing Directive 2009/125/EC of
the European Parliament and of the Council with regard to ecodesign requirements for
water pumps.
2.6.1 Introduction
SPX Flow Technology Assen B.V. is an associate member of the HOLLAND PUMP
GROUP, an associate member of EUROPUMP, the organization of European pump
manufacturers.
Europump promotes the interest of the European pump industry with the European
institutions.
Europump welcomes the aim of the European Commission to reduce eco-impact of
products in the European Union. Europump is fully aware of the eco-impact of pumps in
Europe. For many years the ecopump initiative is one of the strategic columns in the work
of Europump. From the first of January 2013 the regulation is coming into force
concerning minimum required efficiencies of rotodynamic water pumps. The regulation
sets minimum efficiency requirements on water pumps set out under the Ecodesign
Directive for energy related products. This regulation mainly addresses manufacturers of
water pumps placing these products on the European market. But as a consequence
customers may also be affected by this regulation. This document gives necessary
information related to the coming into force of the water pump regulation EU 547/2012.
2.6.2 Implementing Directive 2009/125/EC
• Definitions:
“This Regulation establishes eco-design requirements for the placing on the market of
rotodynamic water pumps for pumping clean water, including where integrated in other
products.”
“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);”
‘End suction water pump’ (ESOB) means a glanded single stage end suction
rotodynamic water pump designed for pressures up to 1600 kPa (16 bar), with a specific
speed ns between 6 and 80 rpm, a minimum rated flow of 6 m3/h, a maximum shaft
power of 150 kW, a maximum head of 90 m with nominal speed of 1450 rpm and a
maximum head of 140 m with nominal speed of 2900 rpm;
‘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;

16 General CL-CBH/EN (1901) 7.6
‘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;
‘Vertical multistage water pump’ (MS-V) means a glanded multistage (i > 1) rotodynamic
water pump in which the impellers are assembled on a vertical rotating shaft, which is
designed for pressures up to 2500 kPa (25 bar), with a nominal speed of 2900 rpm and
a maximum flow of 100 m3/h;
‘Submersible multistage water pump’ (MSS) means a multistage (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 2900 rpm, at operating temperatures
within a range of 0°C and 90°C;
This Regulation shall not apply to:
1 water pumps designed specifically for pumping clean water at temperatures below -
10°C or above +120°C;
2 water pumps designed only for fire-fighting applications;
3 displacement water pumps;
4 self-priming water pumps.
• Enforcement:
In order to enforce this there will be a Minimum Efficiency Index (M.E.I.) criteria set for
the above list of pumps.
The MEI is a dimensionless figure that is derived from a complex calculation based on
the efficiencies at BEP (Best Efficiency Point), 75% BEP & 110% BEP, and the specific
speed. The range is used so that manufacturers do not take an easy option of providing
good efficiency at one point i.e. BEP.
The value ranges from 0 to 1,0 with the lower value being less efficient, this provides the
basis of eliminating the less efficient pumps starting with 0,10 in 2013 (the lowest 10%)
and 0,40 (the lowest 40%) in 2015.
The MEI value of 0,70 is classed benchmark for the most efficient pumps in the market at
the time of developing the directive.
The milestones for the MEI values are as follows;
1 1st January 2013 all pumps shall have a minimum MEI value of 0,10;
2 1st January 2015 all pumps shall have a minimum MEI value of 0,40.
The most important point of this is that unless the pumps comply then they
will not be allowed to have a CE marking.
• Part Load Performance
It is common practice that pumps spend much of their time working away from their rated
duty, and efficiency can fall off rapidly below the 50% duty point, any scheme should take
account of this real life performance. However, manufacturers need a pump efficiency
classification scheme that makes it impossible to design pumps with a steep fall off in
efficiency either side of the BEP point in order to claim a higher efficiency than would be
typical of real life operation.

CL-CBH/EN (1901) 7.6 General 17
CombiLine-CombiBlocHorti
• ‘House of Efficiency’
The decision scheme ‘House of Efficiency’ takes into account design and application
purposes as well as the pump minimum efficiency dependence on flow. The minimum
acceptable efficiency is therefore different for each pump type. The pass-or-fail scheme
is based on two criteria A and B.
Criterion A is the pass-or-fail minimum efficiency requirement at the best efficiency point
(BEP) of the pump:
Where
Criterion B is the pass-or-fail minimum efficiency requirement at part load (PL) and at
overload (OL) of the pump:
Therefore a method is devised what is called a “house of efficiency” scheme that also
requires pumps to pass efficiency thresholds at 75% and 110% of rated flow. The
advantage of this is that pumps will be penalised for poor efficiency away from rated
efficiency, hence it will take account of real life pump duties.
It should be stated that while the scheme may appear complicated at first sight, in
practice it has been easy for the manufacturers to apply the scheme to their pumps.

2.6.3 Energy Efficient Pump Selection
In selecting the pump, care should be taken to ensure that the duty point required is as
close as possible to the pump’s Best Efficiency Point (BEP). Different heads and flows
can be achieved by changing the diameter of the impeller and thereby eliminating
unnecessary energy loss.
The same pump can be offered at different motor speeds to allow the pump to be used
over a much wider range of duties. For instance, changing from 4-pole motor to 2-pole
motor will enable the same pump to deliver twice as much peak flow at 4 times the head.
Variable speed drives allow the pump to operate efficiently over a wide range of speeds
hence duties in an energy efficient manner. They are particularly useful in systems where
is a variation in required flow.
A very useful tool for energy efficient pump selection is the downloadable software
program “Hydraulic Investigator 2” from the SPXFLOW website.
Hydraulic Investigator is the selection guide for centrifugal pumps and search by pump
family and pump type starting from entering required capacity and head. Further refine
the pump curves to find the pump that meets your specification.
The default setting of applicable pump types is prioritized on highest efficiency. In the
standard automated selection procedure the optimum (trimmed) impeller diameter is
calculated already, where applicable. Manually the rotating speed can be adjusted as
well when a variable speed drive is preferred.
Example:
Curve 1: performance at maximum impeller diameter and 2960 rpm;
Curve 2: performance at required duty point (180 m3/h, 30 m) with trimmed impeller,
power consumption 18,42 kW;
Curve 4: performance at required duty point with maximum diameter and reduced
rotating speed (2812 rpm), power consumption 18,21 kW.
