API PLAN-53B Accumulator-based System
Basic Features
- Measuring Media: Compatible with variable barrier fluid
- Function: API Plan-53B accumulator-based seal support systems utilize a bladder to maintain system pressure to pressurized dual seals and absorb barrier fluid thermal expansion while separating the pressurizing gas and barrier fluid. A range of heat exchangers can be packaged with the system, selection dependent on available plant utilities.
- Application: Process pumps
- Standard: API 682 / ISO 21049: Plan 53B
- Model NO.: PLAN-53B
Product Detailed Description
API Plan 53-B is designed in accordance with API 682. Standard tubing or welded pipe construction and optional flanged connection. Pressurization is by means of a pre-loaded bladder accumulator. The nitrogen is separated from the barrier medium by membranes in the accumulator: nitrogen cannot get into the barrier medium or process medium. Barrier pressure is created without any need for connection to a nitrogen supply. Available with finned tube, water or air coolers with fan. Modular system: combination with a wide range of system components/instruments possible.
