PTFE Bellows Chemical Pump Seal
The PTFE Bellows Chemical Pump Seal is a mechanical seal designed for aggressive chemical service. It features a welded PTFE bellows assembly that functions as both the secondary seal and the axial flexibility component. This design eliminates the need for elastomers, providing compatibility with highly corrosive and high-purity fluids. The seal is engineered to handle a wide range of acids, caustics, and solvents at temperatures up to 180°C. Standard configurations include silicon carbide, alumina ceramic, or carbon faces. It is suitable for sealless pump applications and aggressive chemical transfer services where elastomer compatibility is limited.
Our Jiaxing Burgmann seals are high-qualified due to we strictly follow the DIN24960, ISO3069, EN12756, API628 standards.
If the seal is not the one you need, contact us and inform us your seal model or drawing, material, shaft size for quotation. We will advise and offer corresponding mechanical seals.
Customized products and OEM is welcomed.
We offer factory price, high quality, fast delivery and best services.

Q1: What are the key design features of a PTFE Bellows Chemical Pump Seal?
A1: This seal features a welded PTFE bellows that serves as both the secondary seal and the axial flexibility mechanism. This design eliminates the need for elastomeric components, providing complete chemical resistance. The construction typically includes high-grade PTFE for the bellows and advanced ceramic or silicon carbide for the sealing faces.
Q2: In which applications is the PTFE Bellows Chemical Pump Seal primarily used?
A2: It is specifically engineered for handling aggressive chemicals across various industries, including chemical processing, pharmaceutical manufacturing, semiconductor production, and wastewater treatment. Typical applications involve acids, solvents, caustics, and other corrosive media where elastomer compatibility is limited.
Q3: What are the standard operating limits for a PTFE Bellows Chemical Pump Seal?
A3: Standard operational parameters typically include temperature ratings from -50°C to 180°C, pressure capabilities up to 1.6 MPa, and maximum surface speeds of 20 m/s. Specific limits may vary based on seal configuration and material combinations.
Q4: What material benefits does PTFE provide for chemical pump seals?
A4: PTFE offers exceptional resistance to virtually all chemicals, including strong acids, bases, and solvents. It maintains stability across a wide temperature range and exhibits low friction characteristics. The material's non-stick properties also help prevent clogging and material buildup in demanding applications.
Q5: How does the PTFE bellows design address challenges in sealing aggressive media?
A5: The one-piece welded PTFE bellows eliminates potential failure points associated with elastomeric secondary seals. This monolithic construction ensures reliable performance when handling aggressive chemicals, high-purity fluids, and applications where minimal product contamination is critical.
Q6: What face material options are available for the PTFE Bellows Chemical Pump Seal?
A6: Common sealing face materials include reaction-bonded silicon carbide, sintered silicon carbide, alumina ceramic, and premium-grade carbon. Selection depends on specific chemical compatibility requirements, abrasion resistance needs, and operational parameters such as temperature and pressure.
Q7: What are the advantages of an externally mounted PTFE bellows seal?
A7: External mounting simplifies installation and inspection procedures while allowing for operation in limited space applications. This configuration facilitates easier maintenance and provides better heat dissipation compared to internally mounted seals.
