Lanshen Group Co., Ltd., founded in 1958, is a national environmental protection enterprise and a high-tech enterprise. As a manufacturing enterprise for submersible sewage pumps and agitators, after years of development, it has formed a mass production capacity of pump products, complete sets of water treatment machinery, mining equipment and high and low voltage electronic control products, and can produce sewage plants on their own and more than 70% of the equipment in the pump station.

Using scientific and modern management methods, Lanshen Group has successively passed the EU CE certification, ISO9001: 2008 international quality system certification, ISO14001: 2004 international environmental management system certification, GB/T28001-2001 occupational health and safety management system certification, and national mandatory products. 3C certification, water pump production license, hydraulic metal structure production license and other related certifications.

Since cooperating with Germany's ABS Pump Company to produce submersible sewage pumps in 1985, Lanshen Group has insisted on independent technological innovation and has core technologies in the research and development, production and manufacturing of submersible pump products. It owns more than 140 national patents. A national-level postdoctoral research station and a Jiangsu Provincial Enterprise Academician Workstation were established. The Group's Fluid Technology Research Institute has been recognized as the Jiangsu Provincial Water Pump Engineering Technology Research Center and the Jiangsu Provincial Enterprise Technology Center. Completed the research and implementation of national "863 Science and Technology Plan" and other projects, and was a qualified enterprise for the acceptance of the Torch Plan project of the National Science and Technology Commission, a technical support unit for the "submersible sewage pump" of the National Science and Technology Commission, and implemented the treasury bond project in 1998 to build an advanced domestic Water pump, water treatment equipment and electrical control cabinet testing center. Especially in the industry, it is the first to apply PDM technology, CFD flow field analysis technology, and finite element analysis to actual work. Through five-axis linkage CNC technology processing, the product research and development efficiency has been improved. The technology is at the leading level in China, and domestic pumps and water treatment are used. The technological development of the equipment industry has played a positive role in promoting it.

Lanshen Group takes social responsibility as its responsibility and revitalizes the national environmental protection industry as its goal.
