What Are Chemical Seals?
Chemical seals, also known as diaphragm seals, serve as a protective barrier between pressure measurement instruments and harsh process media. These seals prevent corrosive, high-viscosity, or contaminated fluids from damaging sensitive instruments while maintaining accurate pressure readings.
Blanes Pressure Solutions offers high-quality chemical seals designed for industries where standard pressure gauges and transmitters would fail due to extreme conditions.
How Chemical Seals Work
A chemical seal consists of a flexible diaphragm that isolates the process fluid from the pressure-measuring instrument. The space between the diaphragm and the instrument is filled with a transmission fluid, allowing accurate pressure readings without direct exposure to the process medium.
This mechanism ensures that even the most aggressive chemicals or high-temperature fluids do not compromise the performance of pressure instruments.
Key Benefits of Chemical Seals
1. Corrosion Resistance
Chemical seals are manufactured using materials such as stainless steel, Hastelloy, Monel, and PTFE, ensuring resistance against highly aggressive chemicals, acids, and solvents.
2. Prevention of Clogging
Ideal for high-viscosity or crystallizing fluids, chemical seals prevent clogging and buildup that could affect measurement accuracy and instrument longevity.
3. Extreme Temperature Protection
Chemical seals provide thermal isolation, making them suitable for environments with extreme heat or cold, such as steam-based systems or cryogenic applications.
4. Improved Accuracy and Longevity
By preventing direct exposure to process media, chemical seals enhance the durability and reliability of pressure instruments, reducing maintenance costs and downtime.
5. Hygienic and Sanitary Applications
In industries like pharmaceuticals, food, and beverages, chemical seals ensure process fluids do not contaminate measurement instruments, maintaining hygiene and compliance with industry standards.
