MAG 075 MagneDrive® II Series

Magnetic agitator with shaft of high pressure laboratory reactors


The MagneDrive® agitator uses rare earth magnets, permitting packless mixing at higher speeds and with higher viscosity fluids. Outer drive magnets, rotated by a motor driven belt exert powerful attraction on the encapsulated inner magnet assembly. As the outer drive magnets are rotated, the inner magnets are actuated, resulting in rotation of the agitator shaft.

Contamination-free mixing: Packless design eliminates shaft packing and need for lubrication.

Zero leakage to atmosphere: The MagneDrive® is a sealed system, closed to the atmosphere, so even sensitive fluids can be processed safely.

Continuous, high speed operation: No need to shut down in mid-reaction to change failed packing.

Liquid Cooled: Water cooling (user supplied) for over-temperature protection of magnets and bearings. Cooling flow is not always required and can vary depending on vessel operating temperature and drive speed.
