10. Technical data

Voltage variants, rated voltages
1 x 220-240 V.
3 x 380-415 V.
Voltage tolerances
- 10 %/+ 6 % of rated voltage.
Mains frequency
50 Hz.
Enclosure class
CHV pump motor: IP54.
Pressure switch: IP54.
Sound pressure level
The sound pressure level of the pump is below 70 dB(A).
The sound pressure for two pumps can be calculated as follows:
L = L + 3.
max pump
Liquid temperature
0 °C to +40 °C.
Ambient temperature
0 °C to +40 °C.
Operating pressure
Maximum 10 bar.
Minimum inlet pressure
In accordance with the NPSH curve plus other losses and a
safety margin of at least 0.5 metres (1.64 feet) when pumping
airless water.
The safety margin should be increased when air-containing water
is pumped.
Maximum inlet pressure
The actual inlet pressure plus the pressure when the pump is
operating against a closed valve should always be lower than the
maximum operating pressure, i.e. 10 bar.
Start/stop frequency
Maximum 100 per hour.
Liquid temperature and operating pressure may be limited by the
diaphragm tank (or bladder tank).
For further technical details, see installation and operating
instructions for CHV pumps.
