Tianjin Gamma Electric Submersible Pump LLC is an enterprise dedicated to technological innovation. It is composed of experts who have been engaged in the research and development of submersible oil pumps for more than twenty years, and its core technology is the development and research of submersible oil pump motors. The technical personnel are senior professionals who have been engaged in the design, development, production, manufacturing, and quality control of crude oil submersible electric pumps for many years and master relevant technologies. After nearly eight years of unremitting efforts, Tianjin Gamma Machinery Factory has achieved remarkable results. In 2012, it was renamed Tianjin Gamma Electric Submersible Pump LLC.

Our company's products have registered the "Green Brand" trademark and are known in the industry as "Green Brand" submersible pumps. Tianjin Gamma Electric Submersible Pump LLC has its own multiple patented technologies and has obtained the "National Industrial Product Production License", "Explosion-proof Certification", "China Compulsory Certification", and "Quality Management System Certification". The Green Brand submersible oil pump has been listed as a scientific research project in Tianjin and has obtained the "Tianjin Independent Innovation Product" certificate, and has received special funds from the government for many times.

Over the past eight years, this project has received encouragement and support from the leaders of Sinopec and PetroChina: At the "Green Brand Submersible Oil Pump Achievement Appraisal Meeting" organized by the Tianjin Science and Technology Commission, the experts' evaluation opinions are that "the product performance indicators have reached the level of similar foreign products and can replace imported products", and "this achievement has reached the leading level in China in terms of technology". The newly approved scientific research project "Large Flow Submersible Oil Pump" in 2011 has reached the international leading level and has been recommended to the Ministry of Science and Technology of China by Tianjin and approved. It is used in Tiechao Expressway in Liaoning Province; in Daguang Expressway; in the entire Shanxi Province of Sinopec; and in the entire Lanzhou-Zhengzhou-Changsha Product Oil Pipeline of PetroChina.

The Green Brand submersible oil pump has been installed in hundreds of stations and nearly 4,000 submersible oil pumps in China. It is installed in the high-cold station of PetroChina 200 meters away from the border in the northernmost part of China, north of Mohe; in the southern part, it is installed in Changjiang Haiwei Station in Hainan Province; it is installed in the southeastern coastal provinces; in the western part, it is installed in high-altitude gas stations in Yunnan and Guizhou; especially in the entire railway near the tropical equator in Angola. The Green Brand submersible oil pump is gradually covering all parts of the country and even the world. It has obtained the qualification to be shortlisted by Sinopec, and has also received strong support from refueling machine enterprises such as Zhengxing, Tokheim, Sanying, Furen Hi-Tech, Rongxing, and Jialijia, and has won the favor of more than 300 dealers in more than 20 provinces across the country.
