Magnetic Coupling Drive Agitator and Mixer

The Magnetic Coupling Drive Agitator and Mixer LEMCDAM is an agitator installed at the center of an industrial reactor and driven through a magnetic coupling, for high pressure applications on vessels from 1000 L to 50 m³. The coupling transmits torque from the external motor to the agitator shaft through a closed containment wall, so the shaft never penetrates the pressure boundary and there is no packing gland or mechanical seal to leak or wear.

How it works

An outer rotor carrying permanent magnets is turned by the motor. Magnetic flux crosses the sealed containment wall and drives an inner rotor mounted on the stirrer shaft, which turns synchronously. The result is a static seal with zero leakage and low energy cost. The LEMCDAM is the MPB type with belt drive, the arrangement used for higher torque: motor power 7.5 to 110 kW, torque 400 to 7000 N·m and stirrer speed 0 to 500 rpm. The coupling is rated from full vacuum to 200 bar and from -40 °C to +350 °C, and a cooling jacket is designed in for high temperature service.

Materials are selected for resistance to the process chemicals: SS304, SS316, Hastelloy C, Inconel, Monel and titanium are listed, with carbon steel, nickel and zirconium also available. The connecting size to the reactor depends on the vessel size and on the model of the magnetic coupling drive, and is confirmed for each project.
