4.2 Product information
4.2.1 Product information as per Regulation No. 1907/2006(REACH)
For information as per chemicals Regulation (EC) No. 1907/2006 (REACH), see https://
www.ksb.com/ksb-en/About-KSB/Corporate-responsibility/reach/ .
4.2.2 Product Information as per Regulation No. 547/2012 (for water pumps with a
maximum shaft power of 150kW) implementing "Ecodesign" Directive 2009/125/EC
▪Minimum efficiency index: see name plate, key to name plate
▪The benchmark for the most efficient water pumps is MEI ≥ 0.70.
▪Year of construction: see name plate, key to name plate
▪Manufacturer’s name or trade mark, commercial registration number and place
of manufacture: see data sheet or order documentation
▪Product’s type and size identificator: see name plate, key to name plate
▪Hydraulic pump efficiency (%) with trimmed impeller: see data sheet
▪Pump performance curves, including efficiency characteristics: see documented
characteristic curve
▪The efficiency of a pump with a trimmed impeller is usually lower than that of a
pump with full impeller diameter. 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.
▪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 dismantling, recycling and disposal after decommissioning:
