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.
The values in the table below apply to
Note
single-head pumps and twin-head pumps in
single-head operation.

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

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 < 3.5 mA.
leakage
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.
