Company profile

Dongyang Jinsuo Pump Industry Co., Ltd., formerly known as Dongyang Screw Pump Factory, Zhejiang Province / Zhejiang Dongyang Faxing Mechanical & Electrical Co., Ltd., was founded in 1975. It was one of the earliest enterprises in China’s screw pump industry to specialize in the production of complete single-screw pump units and spare parts.

Our company’s technical leader is Senior Engineer Hong Zhensheng, who previously served as the technical director of the National Single-Screw Pump Joint Design Project, received the National Science Conference Award in 1978, holds the title of Professor-Level Senior Engineer, and is a ministerial-level model worker. In 1997, he drafted China’s industry standard JB/T8644--1997 “Single-Screw Pumps,” and in 2000, he applied for a patent for the TYG-type single-screw pump. The term “nominal diameter” for rotors was proposed by Senior Engineer Hong Zhensheng, and the “rubber stator injection molding method” pioneered by our company remains the most widely used process standard among domestic peers.

From 1978 to 2014, our company successively replaced more than 200 originally imported screw pumps at the Acrylic Fiber Plant of Shanghai Petrochemical General Plant. Since 2015, we have supplied over 30 energy-efficient, high-performance single-screw pump units for the technical upgrade of the Shanghai Petrochemical Acrylic Fiber Plant.

To date, our company has been supplying single-screw pumps, spare parts, and maintenance services to Shanghai Petrochemical and Yizheng Chemical Fibre for over 40 years.

In 2015, we supplied 50 G85-1 single-screw pumps under a single contract for the technical upgrade of the Karamay Oilfield. At the same time, our single-screw pumps were also sold to oilfields in Russia.

In 2017, we acquired the key equipment and technology for manufacturing single-screw pumps from Xi’an Haixing Pump Industry.

From 2018 to the present, our company has supplied thousands of sets of complete single-screw pump systems, as well as core components such as rotors and stators, to domestic industries including petroleum and petrochemicals, wastewater treatment, and others.

Currently, our company has also achieved outstanding results in the research and development of high-temperature single-screw pumps and carbon fiber screw pumps.

With our technology, equipment, experience, and capabilities, we are well-positioned to provide superior screw pumps and technical support to the domestic and international petroleum and petrochemical industries, as well as to sectors such as wastewater treatment, papermaking, and food and pharmaceuticals.
