Performance curves
The guidelines below apply to the performance curves
on pages 42 to 56:
• Test liquid: airless water.
• The curves apply to a density of ρ = 983.2 kg/m
3
and a liquid temperature of 140 °F (60 °C).
• All curves show average values. If a specific
minimum performance is required, individual
measurements must be made.
• The curves apply to a kinematic viscosity of μ =
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, you
can set the constant- and proportional-pressure curves
in steps of 0.1 m head on the operating panel or with
Grundfos GO.
Energy efficiency index (EEI)
MAGNA3 is energy-optimized and complies with the
EuP Directive (Commission Regulation (EC) No
641/2009) which has been 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.
MAGNA3 with its AUTO
ADAPT
function is the preferred
choice for large heating systems and a true efficiency
frontrunner.
Figure 57 shows the energy consumption index for a
typical circulator pump compared to the various EEI
limits.
Fig. 57 Energy consumption index, single pumps
With an energy efficiency index (EEI) well below the
EuP benchmark level, you can achieve energy savings
of up to 75 % compared to a typical circulator pump
and thus a remarkably fast return on investment.
