3. Operating Conditions

3.1. Ambient Temperature

Ambient temperature:  O 't)

3.2. Relative 

humidity  (RH)

Max. humidit)r: 95%

3.3. Medium (liquid delivery) temperature

Liquid 

delivery 

temperature: 

+2 't)

To avoid condensation in control box and the stator. the temperature of liquid pumped
by the motor pump must be always higher than ambient temperature.

3.4. System  Pressure

Maximum 

pressure 

LOMpa(IObar)

3.S. 

Degree of Protection

IP42

3.6. 

Inlet 

Pressure

3.7. Pumping  Liquid

The pumping liquid includes thin.  clean,  non-corrosive and non-explosive  I iquid

which shallnot contain any solid  particles. fiber or mineraloll. and the pump must

definitely not be used to pump  inflammable  liquid such as rapeseed oiland  gasoline.

If the pump is used in a place with relativelyhigh viscosity,  the  pump  has  lower

performance. So when choosinga  pump.  the viscosityof  liquid  must  be taken  into

account.
