Abstract
A pump end assembly has a centrifugal pump and a motor separated by a chamber. The chamber contains a thrust bearing as well as an intake for the pump. Fluid flowing into the intake flows through the thrust chamber and to the inlet of the pump. Some of the fluid also flows through the thrust bearing for lubricating the thrust bearing.
