Our company was one of the first in China to introduce Italian jet pumps and has made significant contributions to improving jet pump designs. Specifically, we upgraded the original Italian jet pump flow channel nozzle system from a 6mm to a 9mm flow channel system. This modification resolved issues such as machine jamming caused by small stones, which were unsuitable for the Chinese market, and significantly enhanced suction performance and sand-passing capability. This technical upgrade was also adopted by the Italian side. Additionally, our company pioneered jet pumps with features such as anti-jamming protection and water shortage protection, as well as intelligent pressure-boosting pumps with no-pressure and water-flow switch control. We hold several patents for pump technologies.
