Create a Safer, More Hygienic
    Process Environment with
    Magnetic Mixing Solutions.

    Magnetic Coupling
    Mixing Technology

    SEDNA’s magnetic agitators are engineered for high-precision pharmaceutical and bioprocess applications where zero leakage and contamination-free performance are essential.
    Unlike conventional seal-type agitators, SEDNA’s magnetic coupling technology uses permanent magnets to completely separate the drive unit from the process fluid. This fundamentally prevents leakage and external contamination during mixing.
    Designed for demanding industries such as pharmaceuticals, biotechnology, food & beverage, chemicals, and semiconductors, this technology complies with ASME BPE, 3-A, and CE standards, ensuring clean, efficient, and reliable long-term mixing performance.

    Principle of Magnetic Agitators

    SEDNA ENG’s magnetic agitators use magnetic coupling technology
    to deliver stable mixing performance in a fully sealed structure.

    • Drive Unit (The external magnet)
    The external magnet connected to the drive motor rotates and transfers torque
    to the internal magnet without physical contact through the sealed barrier
    • Welding plate
    The stainless-steel Welding plate separates the process fluid
    from the drive unit, preventing leakage and contamination without mechanical seals.
    • Impeller Unit (The internal magnet + Impeller)
    The internal magnet rotates by following the magnetic field of the external magnet, driving the connected impeller inside the tank.This enables stable, hygienic mixing without mechanical seals, making it ideal for high-purity and sanitary processes.
