Summary:An electrical submersible pumping (ESP) system for use in a wellbore having a pressure equalization system that employs modules with a bellows. The bellows axially expands and contracts in response to pressure fluctuations encountered in the wellbore. The modules are attachable in series on a lower end of a motor of the ESP to form the string, where the string can range from a single module to a multiplicity of modules, depending on the application. The bellows has a conduit axially inserted through the bellows that includes an umbilical and has an end in pressure communication with the motor.
