Independent testing institutions have verified the hydraulic efficiency, dry running tolerance and long-term anti-corrosion performance of MP, CQF, self-priming pumps and YDW vertical pumps. Test reports match the technical access standards of international EPC engineering contractors. With complete test documents and CE certification, YD products can participate in public bidding projects for industrial wastewater renovation and chemical plant construction in European and American markets. This qualification helps YD step into higher-end global engineering procurement markets instead of only scattered retail orders.
