SO-3 Buffer/Barrier Fluid Reservoir

Description

The SO-3 barrier fluid reservoir is designed to contain barrier fluid for a tandem or double mechanical seal, to provide its cooling and to control mechanical seal performance. The SO-3 barrier fluid reservoir can be used with API Plans 52 or 53 as per API682. For operation under the API 53 Plan, fluid make up manual pump NRP with the installation kit should be additionally specified.

The SO-3 barrier fluid reservoir canto be used as standard for majority applications.

The system can be fitted with instrumentation and control for automatic checking of mechanical seal performance and pump shutdown in case of mechanical seal failure. The instrumentation and control version of SO-3 can additionally include a level sensor, a pressure switch, and a temperature sensor. Sensors and switches are either intrinsically safe or explosion proof depending on customer's order.
