About Us

Hangzhou Qinghua Industrial Co., Ltd., a modernized manufacturer, has long been devoted to developing fluid sealing and centrifugal compressor technology, designing and manufacturing mechanical seals, centrifugal units, pump equipment, etc,. Founded in 2006, her total assets raised up to 60million RMB, including 5.88million RMB of the registered capital. It covers an area of 12,000 SQMs. The organization possesses standard modernized factory, science& research center, company building, which include 10,000 SQMs areas totally, and an excellent technical group. Through more than 100 staffs’ hardworking, the company has achieved great improvement— production capacity, 50,000 units annually.

The yearly sales’ amount is about 5 million USD, demonstrating Qinghua’s worldwide offers and services to Asia, Europe, Africa, America, and the rest of world. A strong research team, which consist of 3 professionals and senior engineers, 12engineers and 40 technicians in our company, helps us to aim at “ Quality-oriented, Scientific management; Customer satisfaction, Industrial leading’’. Following the successful partnership with Shijiazhuang Kingda Pump Industry Group and its research center, organization has established perfect quality control system, which is qualified to ISO9001:2008 quality certification. Meanwhile, the cooperation with Dalian University of dynamical system institute in science and technology was great significant for them to be entitled to China’s National Industrial Production Licenses by General Administration of Quality Supervision, Inspection and Quarantine(AQSIQ) of China, ensuring company’s product quality, which was increasingly upgraded from then on. As a result, they are good recognized in the industry.

In recent years, our business scaled up investment drive as well as production campaign. We bought in Japanese MAZAK NC Lathe with full function and AUTO practice, 4meters double column vertical lathe, 1.8m CNC boring machines in our CNC processing center. As for product quality control, we strengthened quality management, upgraded low, medium, high speed test equipment, created ultrahigh speed test unit, running on a high level.

Networking and activities for sales play a vital role in our company. We have been supplying sets and units about air separation plants for Hangzhou Hengyang Group, supporting mechanical seals for Shang Group, including petrochemical pumps, high pressure boiler (feed) pumps for several years. We also provided services for Shijiazhuang Kingda Pump Industry Group Co., Ltd., for example, mechanical seals for desulphurization pump, slurry pump, dredging pump, clean water pump and other machines’ sealing units. What is more, we developed mechanical seals for Xiangfan 525 Pump Industry Co., Ltd., using to desulphurization pumps, phosphate &compound fertilizer pumps.

Now we have developed a variety of mechanical seals for the purpose of industrial utility, involving pump sealing, centrifugal sealing, dynamical compressor sealing, which allow widespread application and comprehensive practices, ranging metallurgy, mine, petroleum, chemical, electric power, alumina, paper making, shipbuilding, coal chemical, sewage treatment, biological pharmaceutical industries. We provided premium quality equipment, spare parts, and other services to our customers, gained a good reputation from users.
