9. Guide to performance curves
Curve conditions
The guidelines below apply to the performance curves
on pages 42 to 55:
• Test liquid: airless water.
• The curves apply to a density of ρ = 61.38 lb/ft
3
(983.2 kg/m
3
) and a liquid temperature of 140 °F
(+60 °C).
• All curves show average values and should not be
used as guarantee curves. If a specific minimum
performance is required, individual measurements
must be made.
• The curves apply to a kinematic viscosity of  =
0.474 mm
2
/s (0.474 cSt).
• Reference supply voltage: 1 x 230 V, 50 Hz.
• EEI obtained according to EN 16297.
Note: Within the MAGNA3 performance range, the
constant pressure and proportional pressure curves
can be set in steps of 0.1 m head on the control panel
or with the Grundfos GO Remote.

Fig. 52 Energy efficiency index (EEI)
The MAGNA3 is energy-optimized and complies with
the EuP Directive (Commission Regulation (EC) No
641/2009) which will be effective as from 1 January
2013.
For MAGNA3 pumps, the average energy efficiency
index (EEI) is 0.18 with values down to 0.17,
categorized as best in class.
Fig. 53 Old energy label
From 1 January 2013, the old A to G energy label will
be replaced by the new energy efficiency index (EEI).
Only the best of today’s A-labelled circulator pumps
will meet the new requirements.
The MAGNA3 with its AUTO
ADAPT
function is the
preferred choice for large heating systems and a true
efficiency frontrunner.
Figure 54 shows the energy consumption index for a
typical circulator pump compared to the various EEI
limits.
Fig. 54 Energy consumption index
With an energy efficiency index (EEI) well below the
EuP benchmark level. With AUTO
ADAPT
the savings
can be as much as 85 %,
compared to a typical
circulator pump and thus a remarkably fast return on
investment. This means, of course, that the MAGNA3
more than meets the standards of the EuP legislation.
