Pump description
In the wet-running pump all rotating
parts are surrounded by the flow
medium, including the motor rotor.
A shaft seal, which would be subject
to wear and tear, is not required. The
pumping medium lubricates the fric-
tion bearing and cools both bearing
and rotor.
No
motor overload protection is
required.
Even the maximum overload current
cannot damage the motor. The motor
operates non-overloading.
