Current EU Approach
• Water Pumps
–
–
–
–
Focus on product
Pump only without drive or VFD
Legislation in Parliament
Expected European Official Journal Summer 2012
• Heating Circulators
– Focus on Pump, Motor, VFD and Controls
– Regulation in place

What is wanted by EU?
• Quantification of Energy Savings
• Intrinsic product property / scale / index
• Energy evaluation / comparison of
products
– mandatory thresholds
– Labeling/marking

EuP Water Pumps Regulation - draft
Chapter 1
Subject matter and scope
1. This Regulation establishes ecodesign requirements for the
placing on the market of rotodynamic water pumps for
clean water duty, including where integrated in other
products.
2. This Regulation shall not apply to:
(a)
water pumps designed specifically for pumping of
clean water with temperatures below -10°C or
above 120 °C, except as regard to the information
requirements of Annex II, point 2(11) to 2(15);
(b)
water pumps designed only for fire-fighting
applications;
(c)
displacement water pumps;
(d)
self-priming water pumps.

EuP Water Pumps Regulation - draft
ANNEX II
Ecodesign requirements for water pumps
1.
efficiency requirements
(A) From 1 January 2013, water pumps shall have a
minimum efficiency index of MEI ≥ 0.10, when
measured according to Annex III.
(B) From 1 January 2015, water pumps shall have a
minimum efficiency index of MEI ≥ 0.40, when
measured according to Annex III.

Future EU Approach
• Pumps
– Extended Product Approach
– Legislation Draft:
Article 7
Revision
The Commission shall review this Regulation in the light of
technological progress and shall present the result of this
review to the Consultation Forum no later than four years
after its entry into force. The review shall aim at
adopting an extended product approach. …….

What is needed ?
• Load Profile Definition
– Generalized but realistic
• Reference Definition (Base Case)
• Market Figures

13
Definitions
• Within EUROPUMP, a methodology and a draft standard will be
developed for the determination of energy efficiency of pump
units
• Pump units consisting of pump + power drive system (PDS)
are defined as Extended Products
• EEI (Energy Efficiency Index) proposed to quantify energy
efficiency of pump units
• Activities concerning energy efficiency of pump units are called
EPA (Extended Product Approach)
• Mandate in draft legislation of Water Pumps and new EU ErP

Methodology for EEI
• The proposed methodology to determine EEI of pump units
will comprise two alternative ways:
1. test of the complete pump unit
2. calculations based on so-called Semi-Analytical Models (SAMs)
(normally done by the end-supplier of the complete pump unit)
• For application of the 2nd method, two SAMs are needed
• SAM of pumps
• SAM of Power Drive Systems
• Semi-Analytical Model = mathematical description of
component characteristics which only needs limited test
data as input to adapt the model to the real component

15
Semi-Analytical Model of pumps
•
SAM of pumps is based on hydrodynamic fundamentals
and is adjusted by test data at 3 specified flow rates
•
These test data can directly be taken from former tests by
the pump manufacturer already mandatory to quantify
the energy efficiency of the pump itself (EuP)
•
SAM of pumps delivers rotational speed n and shaft
torque T for pump operating conditions
(specified by defined load profiles and pressure control
curves)

What we need on standardization for PDS
• Standard(s) should describe test method(s) for
related PDS losses including information on
tolerances / allowable uncertainties
• Standard(s) should specify supporting points within
related PDS losses = f(T,n)-map suitable for an
interpolation scheme valid within the range of „EEI
pump operating points“
• Standard(s) should clarify the responsibilities and
the procedures to determine and indicate related
PDS losses by motor/frequency inverter
manufacturers
