In a wide range of industries, from pharmaceuticals to chemical processing, efficient and dependable filtration is essential. As operations become more complex and regulatory requirements tighten, manufacturers are turning to advanced filtration systems to ensure quality and consistency. Chemap® filtration systems are designed to meet these demands. However, their full potential is realized only when paired with sealing materials that can match their versatility and performance requirements. This is where Durlon® gasket materials have proven to be a critical component.
Supporting Critical Filtration with Durlon® Sealing Solutions
Chemap® filters are widely used for drying, extraction, heel volume filtration, washing, and sterile processing. These systems are engineered for precision and flexibility, serving sectors such as pharmaceutical production, food and beverage, nuclear, hydro-metallurgy, and chemical processing.
Given the diversity of filtration tasks and the wide variety of fluids involved, Chemap faced the challenge of identifying a gasket material that could support all operational scenarios while maintaining high performance. Their goal was to reduce the number of sealing materials in use, standardize across equipment, and simplify inventory management without sacrificing quality or compliance.
Why Durlon®? Versatility, Compliance, and Durability
Chemap® selected three Durlon® gasket materials based on their performance in chemically aggressive environments, their ability to meet regulatory requirements, and their long-term reliability.
Durlon® 9000 is a highly versatile, filled PTFE gasket that delivers consistent sealing performance in a variety of conditions. It is especially valued for its non-wicking properties, which prevent the absorption of media and help protect flange surfaces from corrosion. Durlon® 9000 offers:
- Excellent chemical resistance across a wide pH range
- FDA compliance for food and pharmaceutical use
- Strong mechanical stability even at elevated temperatures
- Compatibility with a wide range of process media
This material is now Chemap’s primary sealing solution, used in most of their filtration systems due to its adaptability and proven reliability.
Durlon® 9400 is recommended in applications where elevated chemical resistance or ATEX compliance is required. This gasket is designed to withstand aggressive chemicals such as hydrofluoric acid and is formulated with conductive fillers for static dissipation. Durlon® 9400 is well-suited for sensitive filtration environments where safety and regulatory compliance are paramount.
Durlon® 8500 is the gasket of choice for general-purpose sealing at Chemap, offering a high-performance compressed fiber solution that delivers reliable sealing across a variety of media, including steam, water, oils, and mild chemicals. This material provides effective sealing for media including steam, water, refrigerants, oils, and mild acids. Durlon® 8500 offers reliable performance across varied operating pressures and temperatures, making it ideal for utility applications in and around filtration systems.
Streamlining Filtration with Standardized Sealing Solutions
approach to filtration system maintenance and operation. This strategy has delivered several operational benefits:
- Reduced inventory complexity: With fewer gasket types required, stocking and selection have become more manageable.
- Faster turnaround: Maintenance and replacement times have decreased, improving overall equipment uptime.
- Improved performance consistency: Durlon® gaskets have delivered reliable sealing across diverse operating environments, minimizing leaks and failures.
Chemap reports that since implementing Durlon® 9000 as its go-to sealing solution, they have experienced no gasket-related issues across a wide range of applications.
The Results: Reliability, Compliance, and Process Efficiency
The transition to Durlon® gaskets has enhanced the performance and efficiency of Chemap filtration systems across multiple facilities and industries. Most notably, the use of Durlon® 9000 has supported cleanroom standards and regulatory compliance, especially important in pharmaceutical and food production environments.
With improved gasket longevity and chemical compatibility, maintenance requirements have decreased and system reliability has improved. The consistency in sealing performance has also contributed to greater process stability, reduced waste, and lower overall operating costs.
Conclusion: Sealing Success in Advanced Filtration
This case study demonstrates how Durlon® gasket solutions contribute directly to improved filtration outcomes. In complex, high-stakes industries, filtration systems must perform under varied and often harsh conditions. Selecting the right sealing material is essential not only for leak prevention but also for maintaining process integrity, product quality, and regulatory compliance.
For Chemap, the adoption of Durlon® 9000, 9400, and 8500 has enabled them to streamline operations while meeting the unique challenges of multi-purpose filtration. Their success underscores the critical role that sealing technology plays in overall system performance.
