Flex-A-Seal is a leading manufacturer of custom engineered mechanical seals, welded metal bellows and the world's only patented split cartridge mechanical seal. Flex-A-Seal has a full line of component and cartridge seals that have been sealing the industry's most basic and most challenging applications for over 30 years.
Flex-A-Seals patented technology of the world's only two piece fully split cartridge seal allows for the easiest installation of any split seal in the industry. Fully assembled and pressure tested at the factory for the elimination of installation error, reduced downtime and energy savings.
For over 20 years the Flex-A-Gard line has been field proven to add years to the life of equipment operating in the most difficult abrasive and corrosive environments found in Municipal and Industrial waste treatment systems including refineries. Flex-A-Gard produces a complete line of non-metallic parts – Bar Screens, Rakes, Chains, Sprockets, Rails and Grit Collector Buckets.
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.
