Improve the life of your mechanical seals by controlling the seal chambers environment.
The pump’s mechanical seal chamber contains a limited volume of liquid to lubricate and cool the faces of the mechanical seals. The mechanical seals face will generate heat based on the speed, pressure, and the lubricating properties of the pump fluid. Unless this fluid is cooled or replaced, the temperature in the mechanical seals chamber around the seal will increase, which can make it too hot for reliable long term seal performance. To optimize the mechanical seals life, the maximum temperature rise in the fluid around the mechanical seals face should be maintained at 5-15°F (3 to 9° C).
API 610 & 682, ANSI / ASME B73 and ISO 21049 standards have over the years developed piping plans to improve the environment in the mechanical seals chamber.
The following three product recirculation Piping Plans discussed are just a few of the many plans developed by the above standards.
