12. Technical data
Supply voltage
1 x 230 V ± 10 %, 50/60 Hz, PE.
Motor protection
The pump requires no external motor protection.
Enclosure class
IPX4D (EN 60529).
Insulation class
F.
Relative air humidity
Maximum 95 %.
Ambient temperature
0 to +40 °C.
During transport: -30 to +55 °C.
Temperature class
TF110 (EN 60335-2-51).
Liquid temperature
Continuously: -10 to +110 °C.
System pressure
The maximum permissible system pressure is stated on the pump
nameplate:
PN 6: 6 bar / 0.6 MPa
PN 10: 10 bar / 1.0 MPa
PN 16: 16 bar / 1.6 MPa.
Minimum inlet pressure
The following relative minimum inlet pressure must be available
at the pump inlet during operation to avoid cavitation noise and
damage to the pump bearings.
In the case of twin-head operation, the required relative inlet
pressure must be increased by 0.1 bar / 0.01 MPa compared to
the stated values for single-head pumps or twin-head pumps in
single-head operation.
The relative minimum inlet pressures apply to pumps installed up
to 300 metres above sea level. For altitudes above 300 metres,
the required relative inlet pressure must be increased by
0.01 bar / 0.001 MPa per 100 metres altitude. The MAGNA1
pump is only approved for an altitude of 2000 metres above sea
level.
EMC (electromagnetic compatibility)
EN 55014-1:2006, EN 55014-2:1998, EN 61800-3-3:2008 and
EN 61000-3-2:2006.
Sound pressure level
The sound pressure level of the pump is lower than 43 dB(A).
Leakage current
The pump mains filter will cause a discharge current to earth
during operation. I
leakage
< 3.5 mA.
Power factor
The MAGNA1 has a built-in PFC (Power Factor Control) which
gives a cos φ from 0.98 to 0.99, i.e. very close to 1.
13. Disposal
This product has been designed with focus on the disposal and
recycling of materials. The following average disposal values
apply to all variants of Grundfos MAGNA1 pumps:
• 85 % recycling
• 10 % incineration
• 5 % depositing.
This product or parts of it must be disposed of in an
environmentally sound way according to local regulations.
Subject to alterations.
Note
The values in the table below apply to
single-head pumps and twin-head pumps in
single-head operation.

Note
The actual inlet pressure plus pump pressure
against a closed valve must be lower than the
maximum permissible system pressure.
