General notes - ErP (ecological design-) directive
The benchmark for most efficient water pumps is MEI ≥ 0.70The 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.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.Information on benchmark efficiency is available at www.europump.org/efficiencychartsPumps with power consumption > 150 kW or a volume flow QBEP < 6 m3/h are not subject to the Ecodesign Directive for water pumps. Therefore, no MEI value is shown.
