Heavy Duty Diaphragm Seals

Heavy Duty Diaphragm Seal is a robust pressure isolation device specifically designed for harsh and demanding industrial environments involving high pressure, high temperature, and aggressive process media. It isolates pressure instruments such as gauges and transmitters from direct contact with process fluids using a thick, durable diaphragm that transmits pressure through a fill fluid. This ensures accurate measurement while protecting the instrument from corrosion, clogging, and mechanical damage.

Engineered with reinforced construction and high-strength materials like SS 316, SS 316L, Hastelloy, or other exotic alloys, Heavy Duty Diaphragm Seals are ideal for critical applications such as slurry handling, abrasive media, and high-pressure pipelines. Their design ensures long service life, reliability, and consistent performance even under extreme operating conditions.
