Threaded Diaphragm Seals

Threaded Diaphragm Seals

Threaded diaphragm seals isolate pressure measurement instruments from harsh, aggressive, or high-viscosity process media within industrial process control applications. Constructed with a flexible diaphragm housed in a robust threaded connection, these seals transmit pressure accurately to instrumentation via an inert fill fluid. This effectively prevents direct media contact, ensuring precise measurement without compromising instrument integrity or accuracy.

They safeguard sensitive instrumentation against damage, contamination, corrosion, and clogging. By isolating instruments from challenging media, these seals extend equipment lifespan, reduce downtime, improve maintenance efficiency, and enhance overall process safety. Their threaded connection facilitates quick and reliable integration into existing process lines, simplifying installation and maintenance.

Threaded diaphragm seals find extensive use across diverse industries, including chemical processing, oil and gas, pharmaceuticals, water and wastewater treatment, food and beverage production, power generation, pulp and paper, and mining. Their versatile, compact design makes them particularly suitable for applications involving smaller piping systems and locations where space constraints or rapid assembly are critical.

Typical applications include pressure measurement on chemical reactors, pumps, compressors, hydraulic systems, dosing and metering systems, water treatment skids, slurry transport lines, and processing equipment handling corrosive or viscous fluids. By ensuring reliable, accurate pressure monitoring, threaded diaphragm seals significantly enhance operational safety, performance, and compliance.
