摘要： A mixer for an aseptic liquid in a vessel having a wall comprising a weldment post having a distal extremity inside the wall and having a proximal extremity outside the wall. The weldment post has a bore therein extending out through the proximal extremity of the weldment post. A motor driven magnet drive assembly is disposed in the bore in the weldment post. A hub carrying impellers is rotatably mounted on the weldment post. A magnet driven assembly is mounted in the hub and is disposed in close proximity to the magnet drive assembly but is separated therefrom by a liquid-tight seal. The magnet drive assembly includes a plurality of circumferentially spaced apart driven permanent magnets which are caged by bars to prevent movement of the driven permanent magnets with respect to the hub.
