12. Technische gegevens
Voedingsspanning
1 × 230 V ± 10 %, 50/60 Hz, PE.
Motorbeveiliging
The pump requires no external motor protection.
Beschermingsklasse
IPX4D (EN 60529).
Isolatieklasse
F.
Relative humidity
Maximum 95 %.
Omgevingstemperatuur
0 tot 40 °C.
Omgevingstemperaturen onder 0 °C vereisen de volgende
omstandigheden:
•
De mediumtemperatuur bedraagt 5 °C.
•
Het medium bevat glycol.
•
De pomp werkt continu en stopt niet.
•
Voor dubbelpompen is cascadebedrijf elke 24 uur
vereist.
Omgevingstemperatuur tijdens transport: -40 t/m +70 °C.
Bij koeltoepassingen kan condensatie optreden op het oppervlak
van de pomp.
Condensatietoepassing is alleen toegestaan indien de pomp is
ingeschakeld.
Temperature class
TF110 (EN 60335-2-51).
Vloeistoftemperatuur
Continuously: -10 to +110 °C.
Stainless-steel pumps in domestic hot-water systems:
In domestic hot-water systems, we recommend that you keep the
liquid temperature below 65 °C to eliminate the risk of lime
precipitation.
System pressure
The actual inlet pressure and the pump pressure against a
closed valve must be lower than the maximum permissible
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 12: 12 bar / 1,2 MPa
PN 16: 16 bar / 1,6 MPa.
Note: Not all variants are available in all markets.
Test pressure
The pumps can withstand test pressures as indicated in EN
60335-2-51. See below.
•
PN 6: 7,2 bar / 0,72 MPa
•
PN 10: 12 bar / 1,2 MPa
•
PN 6/10: 12 bar / 1,2 MPa
•
PN 12: 12 bar / 1,2 MPa
•
PN 16: 19,2 bar / 1,92 MPa.
Not all variants are available in all markets.
During normal operation, do not use the pump at higher pressures
than those stated on the nameplate.
The pressure test has been made with water containing
anticorrosive additives at a temperature of 20 °C.
Min. voordruk
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 single-head pumps
and twin-head pumps in single-head operation.
In the case of cascade 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 MAGNA3 pump is only
approved for an altitude of 2000 metres above sea level.
Geluidsbelasting
The sound pressure level of the pump is dependent on the power
consumption. Levels are determined in accordance with ISO 3745
and ISO 11203, method Q2.
