A magnetically driven pump and drive mechanism having a rotary driving member with a recess therein and a first magnetic surface thereon, a rotary driven member located in the recess of the driving member and having a second magnetic surface on its periphery, a container located between the drive member and the driven member for preventing the escape of cooling fluids circulated therein, a hub connected to the rotary driven member, at least one port through the hub providing for the passage of fluid from the first side of the hub to the second side of the hub, and a gap between the driven member and the container which provides a second fluid passage between the first side of the hub and the second side of the hub. The port and gap combine to provide a fluid circulation path to allow constant fluid circulation between the first side of the hub and the second side of the hub, thereby cooling the rotary driven member.
