Anhui Changyu Showcases Fluorine Lined Chemical Pumps at 44th Sulfuric Acid Conference

Anhui Changyu strongly promotes the new generation of fluorine-lined chemical pumps, contributing to the development of China’s sulfuric acid industry.
In 2025, Director Wang Aijun led the team to attend the 44th National Sulfuric Acid Technology Conference, aiming to support the development of China’s chemical industry and inject new momentum into the sulfuric acid sector.

Industry Trend

In recent years, China’s sulfuric acid industry has developed rapidly. China has become the world’s largest producer and exporter, accounting for more than 40% of global capacity. It is understandable that under such conditions, large-scale sulfuric acid production and transportation have become a major challenge. The strong corrosiveness and leakage risk of sulfuric acid concern enterprise decision-makers.

Event Details

In today’s market, China’s fluorine-lined pumps have become a very mature product. Especially for specific industries, fluorine-lined pumps are highly specialized products that can effectively solve corrosion, wear, leakage, and cost issues. For example, in the sulfuric acid industry, the CYF pump made of F46 material has several advantages:

1. It uses a co-developed self-flushing anti-clogging double mechanical seal, which, under proper operation, can prevent leakage and corrosion risks.
2. For low-solid high-corrosion working conditions, it provides extremely high pump efficiency.
3. F46 material and FEP material both have excellent resistance to sulfuric acid, ensuring extremely long service life. At this sulfuric acid conference, we focused on UHB, CYF, and CYG series pumps, which attracted significant attention from many industry professionals.

Technology or Advantages

Materials (PTFE / stainless steel, etc.)
Performance (corrosion resistance, wear resistance, etc.)

In Jingxian, the hometown of fluorine-lined pumps in China, through technical exchanges, we have gradually expanded chemically lined pump materials for different working conditions, such as ultra-high molecular weight polyethylene with corrosion and wear resistance, FEP material for highly corrosive media, and PFA material that enhances temperature and wear resistance based on corrosion resistance. China’s fluorine-lined pump industry originated here and has gradually spread nationwide. More than 90% of fluorine-lined pump manufacturers in China derive their technology from us.

Application Scenarios

Director Wang Aijun is very proud and confident in our products. We not only manufacture products but also deliver results. He has led all employees of Anhui Changyu to win numerous large-scale domestic projects.

Quotation:

“This product will significantly improve stability in highly corrosive environments,” said a technical director from a certain company.

Data or Achievements:

It can be seen that in our projects, a large number of UHB and CYF series fluorine-lined pumps are used. High polymer materials are used to handle acid-alkali corrosion and wastewater transport. The technical team leader of a well-known domestic sulfuric acid association has also highly praised Changyu. In corrosion resistance, fluorine-lined pumps are definitely a high-quality choice and a cost-effective alternative to high-strength alloys. Fluorine-lined pump manufacturers are excellent partners for all sulfuric acid production enterprises.

Conclusion

This conference participation marks another important step for Anhui Changyu in advancing fluorine-lined chemical pump technology in the sulfuric acid industry. By continuously improving material systems such as F46, FEP, and PFA, and optimizing pump structures for high-corrosion applications, Changyu is committed to providing safer, more efficient, and longer-lasting solutions for sulfuric acid and other aggressive chemical media. Going forward, the company will continue to strengthen technical innovation and deepen cooperation with industry partners to support the sustainable development of China’s chemical and sulfuric acid sectors.
