What Goes Into the Right Diaphragm Seal?

Selecting a diaphragm seal involves more than choosing a connection size. Haygor evaluates the complete application — from process media and operating conditions to materials, instrumentation, and installation requirements — to help build a seal system engineered for reliable measurement and long-term performance. Proper diaphragm seal selection can help protect pressure gauges, transmitters, and other instrumentation from corrosive, viscous, abrasive, or high-temperature process media. By matching the seal design, diaphragm material, fill fluid, and process connection to the application, Haygor helps customers improve measurement reliability, extend instrument life, and reduce maintenance requirements in demanding industrial environments across critical process measurement applications.

Process Media

The chemical composition, viscosity, solids content, and other characteristics of the process media help determine the appropriate diaphragm, wetted materials, and seal configuration.

Pressure Conditions

Normal operating pressure, maximum pressure, vacuum conditions, and potential pressure fluctuations are considered when configuring a diaphragm seal assembly for the application.

Operating Temperature

Process and ambient temperatures can influence seal construction, system fill, instrument placement, and whether remote mounting or additional temperature-management solutions should be considered.

Wetted Materials

Material compatibility is evaluated around the process environment so the diaphragm and other wetted components are appropriate for the media and operating conditions.

Process Connection

Threaded, flanged, sanitary, in-line, flush, and specialty configurations allow the seal to be matched to the process connection, installation geometry, and maintenance requirements.

Instrument & Installation

Gauge or transmitter type, direct or remote mounting, available installation space, and system arrangement all play a role in the final diaphragm seal configuration.
