Zigong Zhaoqiang Sealing Products Industrial Co., Ltd. is committed to becoming the world's leading sealing technology startup since 2000. The company is located in Zigong National High-tech Development Zone, covering an area of 4,290,000, Registered capital: 30 million yuan. The number of employees: 110

The company is a private joint-stock enterprise, national high-tech Enterprise, and also, member of the National Mechanical Seal Association. It mainly produces seals for petroleum and petrochemical, mining, fine chemicals,  medicine, electric power, machinery and metallurgy, steel and ships.

The company has strong technical research and development capabilities and relies on strategic partners of Tsinghua University and Sichuan University. It has successively researched and developed more than forty utility model patents and more than ten invention patents. It has obtained 16 provincial science and technology innovation projects approval, including two national Torch Program projects and two national key new product projects. Moreover, it has passed ISO9001 quality management system certification, 14001 environmental management system certification, 18001 occupational health and safety management system certification, and the "heavy oil and gas quality outline" certification issued by APIQ1 American Petroleum Institute.

The company specializes in various types of sealing, including flue gas desulfurization system with slurry circulating pump mechanical seal, side-injection stirrer mechanical seal, peripheral pump mechanical seal, alumina industry with various types of slurry pump mechanical seal, coal washing industry with all kinds of low pressure water tank Mechanical seal, potash industry with intermittent external cooling mechanical seal, different types of mineral processing (tailing), manganese ore and other high solid content mechanical seal (wt concentration up to 40% or more), various chemical industry with high temperature and high pressure heavy mechanical seal and domestic. Most importantly, we are engaged in the research, development, design, production, and sales of dynamic sealing technology for transmission and sealing of centrifuges in the alkali industry. It is the largest mechanical seal production and R&D base for heavy-duty high solid content impurity pumps in the country. The company focuses on providing solutions for systems such as flushing, wear, corrosion, and sealing of high solids fluid media.

With the design philosophy of “safety, environmental protection, energy saving, and innovation,” the company has developed a magnetic liquid sealing and supporting an intelligent control system.  With its outstanding advantages such as zero leakage, long life, high reliability and maintenance-free, the products have been widely used in petrochemical, chemical, fine chemical, pharmaceutical, military, and other fields. It fully embodies the advanced nature and originality of the magnetic liquid seal and has been unanimously recognized by customers.

Our company has machining workshops that cover an area of 11,600 square meters. It has a complete set of CNC machining centers and various finishing equipment imported from Japan. Organize production with advanced group technology has made the production process efficient and reliable.

Our company pays attention to quality construction and has a special inspection workshop, which is equipped with professional inspection equipment. All inspection stations use computer-aided testing technology to carefully and accurately collect various performance parameters of magnetic fluid seals to issue reports.

Our company has mature production technology, experienced process equipment technicians and precision measuring instruments. We have full use of ERP production resource management system,  advanced group technology for organizing production,  high-end process technology for machining and intelligent and efficient production and operation process. All these together made producing more than 2000 sets of magnetic liquid seals per year possible.

The company has an efficient and comprehensive sales and maintenance network.

In 2019, we established our Beijing Branch. There are ten sales outlets in Xinjiang, Sichuan, Hunan, Guangdong, Zhejiang, Jiangsu, Shandong, Hebei, Beijing, and Liaoning.
