Abstract
A submersible pumping system includes a pump assembly, a motor and a seal section positioned between the pump assembly and the motor. The seal section includes a clean fluid circulation system, a contaminated fluid circulation system and at least one bag seal assembly. The bag seal assembly includes an upper mounting block, a lower mounting block and a bag seal extending over the upper mounting block and lower mounting block and providing a path for the clean fluid circulation system. The bag seal assembly further includes a mounting plate connected to the upper mounting block that limits the axial travel of the bag seal on the upper mounting block. The bag seal assembly optionally includes a breather tube connected to the mounting plate and extending along the exterior of the bag seal.
