LLCC level around C=70/80% depending on pump category, correspondingto some 6,5 TWh savings
Claimed cost for industry 400 MEUR staged introduction of requirementsis proposed to give time to adapt
Expected savings from proposed measures = 3,4 TWh by 2020 but savingscontinuous = life-time of a pump is 11 years
No labelling proposed as largely OEM market: best of class (C=80%)indication for benchmark level- World in move: voluntary certification pump efficiency scheme in Korea +
mandatory national efficiency standard in China
