Abstract

Provided in accordance with the principles of the present invention, in one preferred embodiment, is a mechanism (10). The mechanism functions in general for providing motive force, and is specially adapted for pumping applications. In particular, the mechanism includes an impeller/pumping section integral with a drive system (16). The mechanism includes a housing (14), and a tube (18) rotatably mounted within the housing. Specifically, the tube mounts in the housing for rotation of the tube relative to the housing, substantially about the tube's longitudinal axis. A power or drive system (16) connected to the tube, and/or forming part of the tube, causes the tube to rotate relative to the housing. The drive system preferably includes a plurality of magnets (42) mounted within the housing, located around the tube, for creating magnetic forces for causing the tube to rotate. One or more impellers (20) mount to the tube. The impellers are adapted to cause fluid flow through the tube when the tube rotates. Tube rotation via the drive system, thus causes fluid flow through the tube.
