Centrifugal separator for downhole pump

Abstract

A separator removes solids from downhole fluid of a wellbore for intake of a downhole pump and allows the removed solids to pass out an outlet downhole of the separator. The separator handles erosion that may occur by having first and second inner bodies disposed in an outer body. The first inner body and extends from intake to a first distal end in the interior, whereas the second inner extends from adjacent an outlet to a second distal end in the interior. A space between the second distal end disposed about the first distal end allows for fluid entering an inlet of the outer housing to pass into the second inner body. A flow body disposed in the space can then produce flow in the downhole fluid separating particulate from the downhole fluid passing from the inlet, to the interior, through the defined space, and to the second passage.
