20110194956 | MECHANISM FOR SEALING PFA SEAL BAGS - A seal section for use in a downhole submersible pumping system includes a housing, a bag support tube extending through the housing, a shaft positioned inside the bag support tube and a bag plate connected to the bag support tube. The bag plate preferably includes an end cap secured to the bag support tube and a locking collar threadingly engaged with the end cap. The bag plate is configured to receive the open end of a cylindrical seal bag manufactured from perflouroalkoxy polymer. The end cap includes a tapered head that tapers from a first diameter that is slightly larger than the inner diameter of the seal bag to a second diameter that is slightly smaller than the inner diameter of the seal bag. This mechanism for securing the seal bag obviates the need for o-ring or other mechanical seals between the seal bag and the bag plate. | 08-11-2011 |
