Blanking flange
*
* A blanking flange is used to blank off the opening when one of the
pumps of a twin-head pump is removed for service to enable
uninterrupted operation of the other pump.

Earth leakage current
I
leakage
< 3.5 mA.
The leakage currents are measured in accordance with EN 60335-1.
EMC EN 55014-1:2006, EN 55014-2:1998, EN 61800-3-3:2008 and EN 61000-3-2:2006.
cos φ The MAGNA3 has a built-in active PFC (Power Factor Control) which gives a cos φ from 0.98 to 0.99, i.e. very close to 1.
Consumption then the pump is stopped
1 to 10 W, depending on activity, i.e. reading the display, use of Grundfos GO Remote, interaction with modules, etc.
4 W, when pump is stopped and no activity.
Sound pressure level ≤ 43 dB(A)
