Abstract
The present invention provides an electrical submersible pump assembly having a submersible pump, a submersible electrical motor drivingly connected to the pump, and a seal assembly disposed between the submersible pump and the motor. The seal assembly is generally of tubular construction and provides fluid communication between the seal assembly cavity and the motor, such fluid communication being in a circuitous path effecting gravity segregation of contaminants including particulate solids in wellbore fluids. The seal assembly thereby controls and minimizes migration of the contaminants into the body of the seal section and on into the motor.
