Positioned in the gap are an isolation seal, an isolation gap section, a primary seal, a primary gap section and a secondary seal. A first pressure control unit is connected to the chamber and to a pressurization device coupled to the isolation gap section for supplying fluid to the isolation gap section from the pressurization device.
