Abstract

A submersible pump assembly has modules, including a rotary pump, an electrical motor, and a seal section located between the motor and the pump. The seal section has a tubular housing with a lower adapter secured to the housing and joining the seal section with the motor. An upper adapter is secured to the housing and joins the seal section with another one of the modules. An inlet port in the upper adapter admits well fluid into the housing. A tubular, flexible compensator element has an upper end sealed to the upper adapter and a lower end sealed to the lower adapter. A communication passage in the lower adapter admits lubricant from the motor into the compensator element. A cap is mounted around the upper end of the compensator element. The cap has a skirt extending radially outward to limit upward expansion of the compensator element.
