Magnetic Stirrer LE-SET/SMS

  • The Magnetic Stirrer LE-SET/SMS with a magnetic coupling is designed to provide effective mixing of fluids under high pressure and high temperature conditions. The magnetic coupling allows for the isolation of electronic components in the system. The torque from the servo drive or stepper motor is transmitted to the stirrer shaft through the magnetic coupling. The magnetic coupling is positioned to provide optimal temperature for the magnetic assembly and to prevent premature wear. An optional cooling jacket can be added to the magnetic coupling.

    The Magnetic Stirrer LE-SET/SMS can be equipped with various types of impellers depending on the mixing medium. When choosing an impeller type, the viscosity of the medium and the speed of the stirrer shaft should be taken into account. For example, radial and axial impellers are suitable for liquids with a viscosity below 5000 cP. As the viscosity of the liquid may change during the reaction, our company offers impellers with variable geometry.

    The Magnetic Stirrer LE-SET/SMS with magnetic coupling is compatible with all chemical reactors. In addition to the standard version, you can order a stirrer with a custom flange design and choose the type of motor. Our engineers will assist with the selection of impeller/turbine and electric motor. The stirrer speed can be adjusted using a control unit. Specialized software is included for convenient and fast setup.

    Features:

    • The main feature of the LE-SET/SMS mixer is the magnetic coupling that allows for mixing in thermobaric conditions. The coupling provides complete sealing, isolates electronic components of the device, and effectively transfers the torque from the servo drive to the shaft.
    • The mixer shaft has a standardized thread and allows for the installation of any compatible impeller. Our engineers will help you choose an impeller or develop a new one.
    • Our mixers are equipped with servo drives or stepper motors, which provide accurate and fast adjustment of the shaft rotation speed. For high-temperature operation, the magnetic coupling can be equipped with additional cooling.

    Options:

    • Coating of contacting surfaces with PTFE
    • Additional cooling of the magnetic coupling
    • Exclusive flange for connection
    • Impeller with variable geometry
    • Shaft with substance feeding channel
    • A magnetic stirrer with a magnetic coupling can be equipped with additional cooling, which is necessary for mixing media at high temperatures (above 250°C).
    • Various types of impellers can be used with the stirrer.
    • Additionally, an impeller with adjustable blade geometry can be installed.
    • The control unit can be equipped with a touch screen, allowing the selection of the stirring speed and braking modes.

    Dismantlable design

    During the operation of the magnetic coupling mixing device, it is necessary to periodically clean the elements that come into contact with the medium. The LE-SET/SMS magnetic stirrer can be easily disassembled into separate parts to remove reaction products and other substances from the surfaces of the shaft, coupling, and impeller.

    IMPELLER

    The impeller of the mixer is threaded to securely connect to the shaft and can be easily replaced with another.

    MIXER SHAFT

    The shaft is connected to the impeller and magnetic coupling via a threaded connection. The shaft has an internal channel for substance delivery through the mixer. Typically, the shaft has an internal cavity that connects to the impeller.

    CONNECTION TO AUTOCLAVE LID

    The magnetic mixer is connected to the chemical reactor via a threaded connection through the central seating hole.

    MAGNETIC COUPLING

    The magnetic coupling is used for the isolated transmission of torque from the electric motor to the mixer shaft.

    ELECTRIC MOTOR (SERVO DRIVE) HOUSING

    The servo drive can be housed in an individual corrosion-resistant casing. The servo drive provides precise and fast regulation of the mixer shaft rotation speed.

    Feeding of substances through the impeller

    The impeller has holes around its perimeter and at the threaded connection. Gases and liquids can be fed directly through the impeller during mixing.

    The impeller is ideal for preparing suspensions using metals. The special shape of the blades prevents the formation of vortex flows, which promotes long-term use of both the autoclave and the impeller. The special shape of the blades allows for preventing the separation of flows. This type of impeller is ideal for mixing gas-liquid mixtures and saturated gases. The impeller allows for gas circulation inside the autoclave. Gas is sucked in from the hollow shaft and discharged from the impeller channels. This impeller is ideal for hydrogenation reactions. This impeller is perfect for mixing medium to high viscosity solids. It is used for emulsification, dispersion, and deagglomeration.
    Radial/axial impeller LE/SET-BAR Series Axial impeller LE/SET-GA Series Axial impeller LE/SET-HA Series Axial impeller LE/SET-LA Series
    This type of impeller is perfect for gas-liquid reactions. Impellers of this type have become widely used in bioreactors and fermentation reactors. This impeller is suitable for fast mixing of substances in a horizontal autoclave. The shape of the blades provides a high level of power. The twisting of the blades allows for the elimination of dead zones during mixing. The impeller can be used in reactors with a large height (relative to the diameter). It is great for suspension and homogenization reactions. This impeller disperses energy evenly throughout the volume and is best suited for gas-saturated suspensions.
