4 Description of the Pump (Set)
4.1 General description
▪ Standardised water pump with shaft seal
▪
Handling clean or aggressive fluids not chemically and mechanically aggressive to
the pump materials.
4.2 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
(
ð Section 4.4, Page 18)
▪ The benchmark for the most efficient water pumps is MEI ≥ 0.70.
▪ Year of construction: see name plate, key to name plate
(
ð Section 4.4, Page 18)
▪ 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
(
ð Section 4.4, Page 18)
▪ 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:

MEI = 0.70 (0.40) for the pump based on the model shown in the Figure are
