Abstract
A sleeve bearing and filter for reducing the wear on a submersible electric pump used to pump fluids containing abrasive materials such as sand. The sleeve bearing receives the upper end of the pump shaft and is equipped with a sintered bronze filter element which restricts the flow of abrasives between the shaft and bearing while permitting sufficient fluid flow for lubrication purposes.
