What is an ErP Pump? October 20, 2019 What is an ErP Pump? The rules and criteria for the European Union’s Ecodesign directive for energy-related products (ErP) have been tightened. The requirements affect the hydraulic efficiency of water pumps with the Minimum Efficiency Index (MEI) and motor efficiency with the International Efficiency (IE) for electric motors, which means both must now carry even higher energy ratings. How do the changes affect Pumps? Water pumps, electric motors and circulators that fail to meet these efficiency requirements cannot be sold within the European Union (EU). That means you can only purchase water pumps, electric motors and circulators on the market that have a lower environmental impact and are more economical to run. From 2013 All water pumps in the scope of this regulation must have a Minimum Efficiency Index (MEI) ≥0.10. Glandless standalone circulators must have a Energy Efficiency Index (EEI) ≤0.27 From 2015 From 1st January, all electric motors from 7.5-375 kW must either meet the IE3 premium efficiency standard or the IE2 higher efficiency standard equipped with a variable frequency drive (VFD). From 1st January, all water pumps in the scope of this regulation must have a Minimum Efficiency Index (MEI) ≥0.40. From 1st August, glandless standalone circulators – and glandless circulators that are integrated in products – must have an Energy Efficiency Index (EEI) ≤0.23. From 2017 From 2017, all electric motors from 0.75- 375 kW must either meet the IE3 premium efficiency standard or the IE2 high efficiency standard equipped with a variable frequency drive (VFD).
