Conditions of use
• Permissible ambient temperature from 0°C to + 40°C.
• Maximum permissible relative humidity (RH) 95%
•
Permissible heating medium temperature +2°C~95°C. To prevent condensation of
steam on the control panel and the stator, the temperature of the heating medi-
um circulating running through the pump must always be higher than the ambient
temperature.
• The permissible maximum pressure in the system is 1.0 MPa (10 bar)
• Protection rating IP 44
• Pump input signal
•
To avoid damaging pump bearings by cavitation, the following minimum pressure
must be maintained at the pump input:
Heating medium temperature [°C] <85°C 90°C
110°C

Heating medium
Thin, clear and non-explosive liquid not causing corrosion does not contain any solid parti-
cles, bres or mineral oil. The pump cannot be used to transport inammable or explosive
liquids such as vegetable oil or petrol. If the circulation pump is used to pump highly viscous
liquid, the pump eectiveness will drop. In such a case, a stronger pump must be used to
obtain proper parameters.
