MP52/53A Series for API 682 Plans 52 and 53A
The MP52 series aligns with API 682 Plans 52 and 53A. The Plan 52 is designed to support liquid buffer fluid for a containment seal chamber that is below below the seal chamber pressure. The Plan 53A is a pressurized system designed to isolate the seal from the process completely by providing liquid barrier fluid at a pressure higher than the seal chamber.
Our seal reservoirs are built to ASME Section VIII standards and are available with ASME U code stamps. Flexaseal Engineered Seals and Systems, LLC provides standard and custom buffer fluid reservoirs that meet API 682 Standards.

How it Works
How Does a Seal Pot Work?
According to API 682 Seal Plan 52, a non-pressurized reservoir system is a protective buffer between the product and the surrounding atmosphere. Several seal systems are used to isolate toxic fluids/gases that, when exposed to the atmosphere, can change state. For this reason, buffer fluid is circulated between the inner and outer seal chambers with a circulating pump.
The MP52/53A Reservoir (Pot) provides buffer fluid to the secondary seal for lubrication under normal operations and serves as an overflow for process fluid in a failure scenario. The reservoir can also be equipped with level, pressure, and temperature instrumentation to provide real-time process feedback on mechanical seal health.
