3.3.2. Motor
The pump motor consists of the stator and shaft with
impeller assembly. The cable for the power supply is de-
signed for maximum mechanical performance in accor-
dance with the characteristic or pump name plate. Both
the cable entries and the line are water-pressure tight to
the depth provided on the name plate. The shaft bearing
assembly is supported via robust, maintenance-free and
permanently lubricated roller bearings.
All motors can also be delivered in an explosion-proof ver-
sion in accordance with FM Class I, Division 1, Groups C
& D.
