The bellows design allows for axial movement, making it ideal for sealing applications where the distance between the sealing surfaces may change due to thermal expansion, vibration, or other factors. Additionally, the PTFE material is able to withstand a wide range of temperatures and harsh chemicals, making it suitable for use in demanding environments.These mechanical seals typically feature a metal component, such as a stainless steel or carbon steel casing, which provides structural support and additional durability. The metal component also helps to dissipate heat generated during operation and provides a surface for the PTFE bellows to compress against for improved sealing performance.Overall, PTFE bellows mechanical seals are a reliable and long-lasting sealing solution for applications that require high chemical resistance and temperature tolerance.As the rotating component turns, the PTFE bellow compresses and expands to compensate for the axial movement of the rotating component. This movement helps to maintain a constant contact pressure between the seal faces, which is essential for effective sealing.PTFE bellow mechanical seals are widely used in applications where the fluid being pumped or mixed is corrosive, abrasive or has a high temperature, as PTFE has excellent chemical resistance and can withstand extreme temperatures. They are also suitable for applications where low friction is required, as PTFE has a low coefficient of friction.
PTFE bellow mechanical seals can be used in a variety of pump and mixer applications in various industries, including:
- Chemical processing: PTFE bellow mechanical seals are commonly used in chemical processing applications that involve corrosive or aggressive chemicals. They are used in pumps and mixers to prevent fluid leakage and ensure safe and efficient operation.
- Food and beverage: PTFE bellow mechanical seals are also used in the food and beverage industry, where the use of FDA-approved materials is required. They are used in pumps and mixers for the processing and handling of food and beverage products.
- Pharmaceutical: In the pharmaceutical industry, PTFE bellow mechanical seals are used in pumps and mixers for the processing of various medicines, including those that are corrosive or aggressive. They are also used in sterile environments where contamination must be avoided.
- Petrochemical: PTFE bellow mechanical seals are used in the petrochemical industry for the processing of various chemicals, including acids, solvents, and hydrocarbons. They are used in pumps and mixers to prevent fluid leakage and ensure safe and efficient operation.
