MINIMUM EFFICIENCY INDEX (MEI)

The SCR, SCRI, SCRN pumps are energy-optimised and comply with the EuP Directive (Commission Regulation (EC) No 547/2012) which has been effective since 1 January 2013. As from this date, all pumps will be classified/graduated in a new energy minimum efficiency index (MEI).

Minimum efficiency index Minimum efficiency index (MEI) means the dimension less scale unit for hydraulic pump efficiency at best efficiency point (BEP), part load (PL) and overload (OL). The Commission Regulation (EU) sets efficiency requirements to MEI 0.10 as from 1 January 2013 and MEI 0.40 as from 1 January 2015. An indicative benchmark for best-performing water pump available on the market as from 1 January 2013 is determined in the Regulation.

•  The benchmark for most efficient water pumps is MEI 0.70.
•  The 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.
