Techniques used to upgrade the MEN/ME range included hydraulic redesign using the latest computational fluid dynamics (CFD) tools.

All 47 sizes of MEN/ME water pumps now meet the Minimum Efficiency Index (MEI) required by the new regulations and feature IE3 motor integration for added efficiency.

 "This update to our MEN/ME family of end suction water pumps aligns with our global focus on energy saving and our commitment to offer efficient, high-performance products to our customers in the European Union," said Bob Hendricks, president, Industrial Pump Operations.
 
The new regulations state that all rotodynamic water pumps designed for pumping clean water, with a power rating up to 150 kW (201 HP) and within a certain range of suction-specific speeds, must be in compliance with limitations on pressure, power, speed and size in order to be CE marked and sold in the European Union.
 
The regulations were announced by the European Commission in 2012, with energy efficiency benchmarks to be first implemented in 2013 and then increased in 2015.
