Flanged Diaphragm Seals

Flanged diaphragm seals are designed to isolate pressure measurement instruments from aggressive, corrosive, viscous, or high-temperature process fluids in industrial applications. These seals incorporate a flexible diaphragm securely mounted within a flanged housing, forming a robust barrier that transmits process pressure to the measuring instrument via a sealed, inert fill fluid. This construction ensures accurate pressure readings without direct exposure of sensitive instruments to harsh media.

Flanged diaphragm seals effectively shield pressure instruments from damage or degradation caused by challenging process conditions by preventing direct contact between aggressive media and instrumentation, thereby enhancing measurement reliability, improving instrument longevity, reducing maintenance and operational costs, and ensuring accurate process control while minimizing downtime risks associated with leaks or instrument failures.

Flanged diaphragm seals are widely used in chemical processing, oil and gas, pharmaceuticals, food and beverage production, power generation, pulp and paper, water treatment, mining, and petrochemical facilities. Their flanged design facilitates straightforward installation, maintenance, and compatibility with standard piping and equipment connections, making them particularly suited for harsh and demanding process environments.

Applications for flanged diaphragm seals include protecting pressure gauges, transmitters, and switches in reactors, tanks, pipelines, slurry systems, sanitary lines, hazardous chemical processing, and high-temperature or corrosive fluid handling systems, ensuring safe, reliable operation and precise pressure measurement.
