ABSTRACT:
A canned pump is described which includes a motor, an impeller, a rotatable shaft, and a high inertia flywheel mounted on the shaft and within a hermetically sealed housing. The flywheel comprises a heavy metal disk made preferably of a uranium alloy and having an inner circumferential annular recess portion. One embodiment employs a radial bearing assembly mounted to a bearing housing member, which also carries a thrust bearing assembly, for bearing surface contact with the inner circumferential surface of a stepped portion of the flywheel assembly. A second embodiment employs a radial bearing assembly mounted on the bearing housing member for bearing surface contact with a journal on the outer surface of the shaft. These arrangements locate the radial bearing assembly within the vicinity of the inner circumferential annular recess portion of the flywheel.
