Europump's Pump Efficiency
Program
HI Annual Meeting 2012St. Petersburg, Fl
Remember the Objective
19/04/23 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission 2
• Save Energy – Selection of properly sized pump– Optimum combination of components– System feedback
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
19/04/23 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission 3
What is wanted by EU?
19/04/23 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission 4
• Quantification of Energy Savings
• Intrinsic product property / scale / index
• Energy evaluation / comparison of products– mandatory thresholds– Labeling/marking
EuP Water Pumps Regulation - draft
19/04/23 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission 5
Chapter 1Subject 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
19/04/23 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission 6
ANNEX IIEcodesign 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 7Revision
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. …….

Working Group
19/04/23 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission 12
• Pump Manufactures - EUROPUMP• Motor Manufacturers• Drive Manufacturers• CEN & CENELEC• Scientific support by Technical
University of Darmstadt
What is needed ?
19/04/23 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission 13
• Load Profile Definition– Generalized but realistic
• Reference Definition (Base Case)
• Market Figures
Definitions
19/04/23 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission 14
• 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 work items
Methodology for EEI
19/04/23 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission 15
• 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
Semi-Analytical Model of pumps
19/04/23 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission 16
• 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
19/04/23 Frank Ennenbach, Sulzer PumpsChairman Europump Standards Commission 21
• Standard(s) should describe test method(s) for related PDS losses including information on tolerances / allowable uncertainties
• Standard(s) should specify supporting points withinrelated 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
