Abstract
An electrical submersible pumping system having a pump, a motor, a shaft connecting the pump and motor. Coaxially stacked rotating impellers and stationary diffusers are coaxially housed within the pump. Radial ports are formed in a hub of the diffusers that direct fluid pressurized by an impeller to a cavity formed on the shroud of the impeller. Axial ports are formed in the shrouds of the impellers that direct fluid from the cavity to a fluid flow passage within the impeller. Strategic placement and sizing of the radial and axial ports balances thrust forces exerted onto the impeller.
