WIKA diaphragm seals are protective devices used to isolate pressure instruments from harsh process media.
They are commonly used with pressure gauges, transmitters, and pressure switches in industrial applications.
The diaphragm acts as a flexible barrier between the process fluid and the measuring instrument.
These seals help protect instruments from corrosion, clogging, crystallization, and high temperatures.
WIKA offers diaphragm seals in threaded, flanged, inline, and sanitary connection designs.
They are manufactured using high-quality materials such as stainless steel, Hastelloy, Monel, and PTFE coatings.
The seals ensure accurate pressure measurement even in difficult operating conditions.
They are widely used in chemical, petrochemical, pharmaceutical, food, and oil & gas industries.
WIKA diaphragm seals can be combined with capillary systems for remote pressure measurement.
They are suitable for both low-pressure and high-pressure applications.
The hygienic models are specially designed for sterile and clean process environments.
WIKA diaphragm seals are protective devices that isolate pressure gauges, transmitters, or switches from harsh process media—such as corrosive,
hot, viscous, or abrasive fluids. They use a flexible metal, plastic, or coated membrane to transfer pressure to the instrument via a filling fluid.
WIKA designs diaphragm seals according to international industrial standards and safety requirements.
These seals minimize maintenance costs by extending the life of pressure instruments.
Their compact and robust construction provides reliable long-term performance.
WIKA diaphragm seals are known for their precision, durability, and high operational safety.
