Abstract
An electrical submersible pump assembly has a seal section coupled to a motor that drives the pump. The seal section has first and second end members spaced axially apart from each other. An outer bellows has a fixed end mourned to the first end member and a floating end that moves axially relative to the fixed end. A rigid, tubular interconnect member has an inner end within the outer bellows and an cuter end fixed to the floating end of the outer bellows. An inner bellows has a floating end secured to the inner end of the interconnect member and a fixed end secured to the second end member. An interconnect evacuation passage extends axially through a side wall of the interconnect member. A first end member evacuation passage extends through the first end member and registers with the interconnect evacuation passage while the outer bellows is contracted.
