Over the past eighteen years since its establishment, the company has relied on technological innovation in the shipbuilding industry to independently develop high-performance marine magnetic drive pumps, addressing the shortcomings of "leakage, dripping, and seepage" in key pump equipment in the field. By leveraging two core technologies—leak-free magnetic drive and medium differential pressure self-circulating cooling—the company has overcome the common issue of leakage in traditional mechanical seals, establishing itself as one of the leading enterprises in the domestic marine leak-free pump sector.
The products have successively obtained CCS Product Type Approval, BV Factory Inspection Type Approval, and product inspection certificates from classification societies in China, the United States, the United Kingdom, France, Germany, Italy, Norway, Japan, Russia, and South Korea. The company has applied for and obtained 2 national invention patents and 30 utility model patents. In 2014, it received the National Standardization Administration's Class I Certificate for Adopting International Standards; in 2021, it was awarded the Jiangsu Provincial Industrial Enterprise Quality Credit A-Level Rating; and in 2024, it received the Excellence Award in the National Machinery Industry Product Quality Innovation Competition organized by the China Machinery Industry Federation. Within the supply chain, the company has helped downstream shipyards and end-users reduce procurement costs and shorten delivery cycles, thereby enhancing the value and competitiveness of the entire industrial chain.
In December 2024, the company's drafted "Technical Requirements for Marine Magnetic Drive Multi-Stage Vertical Centrifugal Pumps" was approved as a group standard project by the China Association of the National Shipbuilding Industry, filling a gap in industry standards.
