Abstract

See full text

A subsea water injection pump includes components that are cooled and lubricated by the process fluid. The pump includes opposing stages of impellers in a “back-to-back” arrangement such that the axial forces of the impeller stages partially or nearly fully offset each other. In some cases, a combination of barrier fluid and process fluid is used for lubrication and cooling.
