The Flexaseal Engineered Seals and Systems, LLC MP53 aligns with pump seal Plan 53. It supplies a liquid barrier fluid to the dual seal assembly at a higher pressure than the seal chamber.
Our barrier seal reservoirs are built to ASME Section VIII standards and we have ASME “U” code stamps available. Our team provides custom and standard barrier fluid systems that are up to API 682 Seal Code.
MP53A supplies a liquid barrier fluid to the dual seal assembly at a higher pressure than the seal chamber. Aside from the pressure different, this unit is very similar to our MP52 model.
Our MP53B unit supplies an external barrier fluid pressurized by a bladder accumulator. This sends clean barrier fluid to the dual seal at a pressure greater than the seal chamber.
- “U” stamp accumulator standard
- 5-10 gallon capacity
- Air- or water-cooled available
- Integral barrier fluid make-up pump
The external barrier fluid is pressurized by a piston accumulator and supplies clean barrier fluid to the dual seal at a pressure greater than the seal chamber.
- Integral head porting eliminates pigtail design
- “U” stamp coded vessel design
- Magnetic level indication available
How it Works
How Does a Pressurized Barrier Fluid Reservoir Work?
A pressurized external barrier fluid reservoir forces circulation of a clean fluid to a pressurized dual mechanical seal. The pressurized fluid lubricates the inner and outer seal faces. Keeping the barrier fluid 25 to 30 psi above the seal chamber pressure ensures lubrication of the inboard seal faces.
The Plan 53 Reservoir can be equipped with level, pressure and temperature instrumentation to provide real-time process feedback on mechanical seal health.
