Grundfos Submersible Pump
ErP ready
The ErP Directive (Commission
Regulation (EC) No. 547/2012),
which went into effect on January
1, 2013, is in compliance with
the SP A, SP 4″ and 6″ pumps
since they are energy-efficient.
From this point forward, all pumps are categorized or graded
according to a new energy efficiency index (MEI).
Minimum efficiency index
A hydraulic pump’s efficiency at the best efficiency point (BEP),
part load (PL, 75% BEP), and overload (OL, 110% BEP) is
measured using the Minimum Efficiency
Index (MEI), a dimensionless scale unit.
The Commission Regulation (EU) establishes
efficiency standards to MEI 0.40 as of January 1, 2015.
The Regulation establishes a
baseline for the top-performing
water pump on the market as of
January 1, 2013, in an indicative manner.
MEI 0.70 is the standard for
the most effective water pumps.
• A pump with a trimmed impeller
often has a lesser efficiency
than a pump with a full impeller diameter.
The impeller will be trimmed to adjust
the pump to a specific duty point,
which will result in less energy being used.
The complete impeller diameter
serves as the foundation for the
minimal efficiency index (MEI).
• When regulated, for example,
by the use of a variable-speed drive
that matches the pump duty to the system,
the operation of this water pump with variable duty
points may be more economical
and efficient.
Applications
The main purpose of SP pumps is to
extract raw water from the ground.
The pumps are set up in wells or boreholes
that are submerged beneath the water.
You may put the pump somewhere
else for industrial uses, such a tank.
The SP A and SP pumps are suitable for the following
applications.
From 1 to 280 m3/h, Grundfos provides
energy-efficient submersible pumps.
