Operation principle
In the CTM pump the torque from the motor shaft is transmitted to the impeller by means
of a magnetic coupling. The drive magnet (1) is fixed on the motor shaft. The magnets
installed in the drive magnet and in the impeller/magnet assembly (2) have different polarity.
When the pump is at rest, the magnets of both parts are aligned. When the motor is started
and the drive magnet starts to rotate, the magnets create an attraction and repulsion force
thus forcing the impeller to rotate. If the impeller gets blocked or the pumped liquid will be
too dense and too much torque will be generated on the motor shaft, the magnet will de-
couple and no damaged will be done to the motor. When the pump will come to a stop, the
magnets will re-couple. Between both magnet assemblies there is located an isolation shell
(3) that separates the liquid side from the motor side.
