Recently, Zhejiang Nanchi Pump Industry Co., Ltd. received heavyweight news of technological innovation: in response to the technological upgrade needs of Nanjing Lejin Magna Easy Drive Automotive Parts Co., Ltd., the company has successfully developed a single screw pump product that can completely replace the Japanese Bing Shen 3ND08G15 model after six months of technical breakthroughs. The new product not only maintains the same fluid conveying accuracy as imported products, but also extends the replacement cycle of the core component stator and rotor from 2 months to more than 3 months, solving the operational pain point of long-term dependence on imported parts for joint venture car companies.
As an automotive parts manufacturer formed by the strong alliance between South Korean LG and German Magna, Nanjing LG Magna Easy Drive was established in 2021 and is located in a modern factory area in Qixia District, Nanjing. Currently, it has a professional team of 200-299 people, focusing on the research and production of core components for new energy vehicle drive systems. Enterprises occupy an important position in the global supply chain system, but the high maintenance cost of replacing the stator and rotor of the Japanese Bingshen single screw pump every two months on the production line has always been a bottleneck restricting capacity improvement. The imported accessories not only have a long procurement cycle, but frequent shutdowns and maintenance also affect the efficiency of automated production lines. "The head of the equipment department of the enterprise admitted that it is urgent to find a more high-performance domestic alternative solution.
Established in 2003, Zhejiang Nanchi Pump Industry has already built a complete technological moat in the field of screw pumps. This national high-tech enterprise with seven series of products is equipped with cutting-edge equipment such as five axis linkage CNC machining centers. Its unique "double helix conjugate line" technology has obtained national patent certification, and its products have broken the import monopoly in more than 30 sub fields such as food and medicine, industrial wastewater treatment, etc. It is worth noting that the company's independently developed fluid transportation solution has helped customers in over 50 countries worldwide achieve significant benefits such as a 30% increase in production efficiency and a 20% reduction in operating costs. In the past five years, sales have maintained an average annual growth rate of 100%.
In this technological attack on Guanzhong, Nanchi Pump Industry has formed a special team led by senior engineers, which uses 3D scanning to restore the precision structure of Japanese products, combined with its independently developed wear-resistant alloy material library, and has undergone 187 bench tests and working condition simulations. The R&D leader revealed, "We found that the ordinary nickel based alloy used in imported products is prone to fatigue wear during the transportation of automotive lubricants. Therefore, we innovatively added a tungsten titanium alloy coating to increase the surface hardness of the stator and rotor by 40%." The final sample sent for inspection ran continuously for 98 days without any faults on the automated production line of Nanjing Lejin Magna, and all parameters fully met ISO9001 standards.
