10. Technical data
Supply voltage
1 x 230-240 V –10%/+6%, 50 Hz, PE.
Motor protection
The pump requires no external motor protection.
Enclosure class
IP 42.
Insulation class
H.
Relative air humidity
Maximum 95%.
Ambient temperature
0°C to +40°C.
Temperature class
TF110 to CEN 335-2-51.
Liquid temperature
Maximum +110°C.
Continuously: +15°C to +95°C.

Continuously: +15°C to +60°C.
To avoid condensation in the terminal box and the
stator, the pumped liquid temperature must always
be higher than the ambient temperature. See the ta-
ble below:
System pressure
Pipe connection:
• UPE 25-40, 25-40 A, 25-60, 25-60 A, 25-80,
32-40, 32-60 and 32-80: Maximum 10 bar.
Flange connection:
• UPE 32-80 F, 40-80 F and 50-80 F: PN 6
(maximum 6 bar) or PN 10 (maximum 10 bar).
• The system pressure is indicated on the pump
flanges.
Inlet pressure
The following minimum pressures must be available
at the pump inlet during operation:
EMC (electromagnetic compatibility)
EN 61 000-6-2.
EN 61 000-6-3.
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.
