Abstract

A vertical rotating system that includes a first vertical shaft that rotates. The first vertical shaft is oriented such that the gravitational force is substantially parallel to the first vertical shaft. A radial bearing extends about a first portion of the first vertical shaft. A first impeller sectioned couples to the first vertical shaft and rotates in a first direction to pump a first fluid. A first stator surrounds the first vertical shaft. The first stator defines a first groove that extends about a second portion of the first vertical shaft. The first groove receives a second fluid. A pressure of the second fluid drives the first vertical shaft away from the first groove.
