Abstract

An electrical submersible well pump assembly has a motor containing a dielectric lubricant. A seal section is mounted to the motor for reducing pressure differential between the lubricant in the motor and the well bore fluid. The seal section has a head on an end opposite the motor. A pump assembly is mounted to the head of the seal section. An intake is located in the head of the seal section for drawing well bore fluid into the pump assembly.
