REGULATION (EU) N. 547/2012 of 25-06-2012 implementing Directive
We,
EBARA PUMPS EUROPE S.p.A., declare under our exclusive responsibility that the following
directive integrates the EC Declaration of Conformity contained in the present manual of
instructions.
Minimum efficiency index:
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.
information on benchmark efficiency is available at :
[www.europump.org].
