Curve conditions
Performance curves
The guidelines below apply to the performance curves.
• 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.

Fig. 15 Energy efficiency index (EEI)
The MAGNA1 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 MAGNA1 pumps, the average energy efficiency
index (EEI) is 0.18 with values down to 0.17,
categorized as best in class.
Fig. 16 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.
Figure 17 shows the energy consumption index for a
typical circulator pump compared to the various EEI
limits.

With the Grundfos GO Remote or a smartphone, it is
possible to get the following information about the
MAGNA1:
• product photo
• pump performance curves
• dimensional sketches
• wiring diagram
• quotation text
• technical data
• PDF files, such as data booklet and installation and
operating instructions.
Note: The GO Remote or Smart phone may be used to
read the QR Code to download product information
from GO CAPS. The MAGNA1 does not communicate
with the GO.
