10. Storing the product
12.1.2
Relative humidity
IP44: The relative humidity must not exceed 95 % in a non-
condensing environment.
The dew point of the air at ambient temperature should al-
ways be lower than the liquid temperature, otherwise con-
densation may form in the stator housing.
K-Version/IPX4D: Condensation is acceptable.
12.1.3 Minimum inlet pressure
To avoid cavitation noise and damage to the pump bearings, the
following minimum pressures are required at the pump inlet port.
Liquid temperature 75 °C 95 °C 110 °C
Pressure
0.005 MPa 0.05 MPa 0.108 MPa
0.05 bar 0.5 bar 1.08 bar
