2.2 Relative humidity of the air (RH)
The maximum humidity is 95%.
2.3 Media (conveying liquid) temperature

.To prevent the control box and stator
from appearing condensate water, the temperature of pump conveying liquid must
be always higher than the ambient temperature.
2.4 System pressure
The maximum is 1.0 Mpa (10 bar).
2.5 Protection Level
IP 44
2.6 Inlet pressure to avoid damage to the pump bearing caused by cavitation noise, the
following minimum pressure should be maintained in the pump inlet:
2.7 Pumping liquid
Thin, clean, non-corrosive and non-explosive liquid does not contain any solid particles,
fibers or mineral oil; the pump should not be used for conveying flammable liquid such
as vegetable oil and gasoline absolutely. If the circulating pump is used for the case of
high viscosity, the pump performance will reduce, therefore, when selecting a pump, the
viscosity of liquid must be considered.
