POINTS TO BE ATTENTIVE

a) The maximum liquid temperature for the standard versions is 60 °C.

b) Avoid that pumped materials (ex. mud, …) are sticked on the motor part of the pump.

This can provoke an abnormal heating of the motor. Clean the pump if this occurs.

c) If air occurs in the discharge hose, it happens that the liquid can not be pumped any

more. In that case, verify if the discharge hose is placed as horizontal as possible (ex.
avoid to large space between the floaters).
