Wernert MONSUN Mag-Drive

Description

Magnetic rotor

The central component is the magnetic rotor with its fluid lubricated bearings located at the casing wall, forming one unit with the impeller and containing no static seal. Hence, common inner shafts, sleeves, separation walls and even the axial bearings which are required on typical magnetic drive pumps can be removed. The axial position as well as the propulsion of the rotor is taken over by a new kind of magnetic coupling with a rotating force of 95 Nm. A brilliant solution!

Isolation shell

An isolation shell of silicon carbide closes the pumps inner area hermetically from the environment and separates both halves of the rotating magnetic coupling. Eddy current losses are not generated.

Bearings

Even for closed-coupled versions, the magnetic driver is supported in greased-for-lifetime roller bearings. Locating the isolation shells opening to the electrical driver’s side allows a broad bearing centre distance. An additional flywheel prevents the magnetic coupling’s tear-off during start-up of the machine.

The closed coupled version is constructed in such a way that the motors shaft is coupled to the magnetic driver within the pump. This allows easy assembly and disassembly of the electrical driver, without the need for de-coupling of the magnetic drive.
