  • Magnetically driven rotating separator
    Patent number: 8940068
    Abstract: A gas-liquid rotating separator has first and second sets of magnetically permeable members magnetically interacting with each other to effect rotation of a separator element. A nonauthorized replacement separator element missing the second set of magnetically permeable members will not effect designated operation, thus ensuring, at maintenance servicing, installation of an authorized replacement separator element.
