6 Description and function

6.1 Description of the product
The pump (Fig. 1) consists of a hydraulic system, a glandless
pump motor with terminal box. All the rotating parts in the
glandless pump are in contact with the fluid, this is also true for
the motor rotor. A shaft sealing, which is subject to wear, is not
necessary. The fluid lubricates the slide bearings and cools the
bearing and the rotor. Motor protection is not necessary. Even
the maximum overload current cannot damage the motor. The
motor is blocking-current proof.
