Abstract
A bearing assembly for use in a deepwell submersible pump, the pump and a method of pumping a geothermal fluid. The bearing assembly is constructed to include a lubricant conveying mechanism, a bearing sleeve and a multilayer bushing. The lubricant is forced between the bushing and a bearing sleeve by the lubricant conveying mechanism that cooperates with the rotation of a shaft used to connect a power-providing motor with one or more pump impellers. In this way, there exists a substantially continuous lubricant environment between the sleeve and bushing to act in a hydrodynamic fashion.
