In order to continuously enhance the core quality of the products and establish a benchmark for high-quality domestic deep well pumps, recently, Jinyu Deep Well Pumps have completed a comprehensive upgrade of their production quality inspection system, establishing a full-process refined quality inspection standard from raw material procurement, component processing, complete machine assembly to factory testing. After the upgrade, the brand has added several testing procedures such as hydraulic performance testing, corrosion resistance and pressure resistance testing, and continuous operation aging testing, to precisely verify the core parameters of each factory-delivered equipment, such as head, flow rate, energy consumption, and sealing performance, to prevent substandard products from entering the market. The strict quality control system has continuously improved the stability, durability, and adaptability of Jinyu Deep Well Pumps’ products, significantly reducing the product rework rate. In the future, Jinyu Deep Well Pumps will continue to adhere to the quality bottom line, with meticulous craftsmanship, high-quality products, and comprehensive services, to provide global users with high-quality overall solutions for deep well water extraction.
