Flanged Diaphragm Seal
Diaphragm Seal With Flange Connection
Flanged diaphragm seals protect pressure sensors or transmitters from corrosion and damage caused by process media, ensuring accurate transmission of pressure signals and meeting the requirements of process control and monitoring.
Flanged diaphragm seals are suitable for a wide range of industrial applications, including chemical, petrochemical, pharmaceutical, and food and beverage industries. They are particularly ideal for corrosive, high-temperature, or high-pressure media.
WINNERS offers flanged diaphragm seals as per ASME B16.5, DIN EN 1092-1, or other standards. We also provide accessories such as flushing rings, capillaries, flanges, and metal diaphragms.

Applications
Flanged diaphragm seals are suitable for corrosive, high-viscosity, crystallizing, or high-temperature pressure media, and are widely used in industries such as chemical, petrochemical, pharmaceutical, and food and beverage.
Advantages of Flanged Diaphragm Seals
Strong sealing: Double sealing (flange + diaphragm) almost eliminates leakage, especially suitable for toxic, flammable or high-value media.
Excellent corrosion resistance: The diaphragm material (such as PTFE, titanium alloy) can resist strong acids and alkalis, reducing the risk of equipment corrosion.
Adapt to extreme environments: Withstand high pressure (up to 40MPa), high temperature (+400°C) and high viscosity, particle-containing media.
Safety and hygiene: Isolate the medium from contact with the outside, in line with the sterility standards of the pharmaceutical and food industries (such as FDA, GMP).
Economical and efficient: The equipment life is extended in long-term use, and the overall cost is lower.
