1. The digestion and absorption of introduced technology in the manufacturing industry are slow, and most enterprises have weak technological innovation capabilities. 57% of the main sources of core technology for mechanical products rely on imports. Although most of the products in China's water pump manufacturing industry have basically achieved independent production and manufacturing, domestic enterprises mostly undertake the low-end processing of products, and the breadth and depth of localization need to be improved. For example, the nuclear grade pump products in the complete sets of nuclear power plants that have begun to be localized and the high-pressure boiler feed water pump core package products in the complete sets of equipment of megawatt supercritical and ultra supercritical fossil-fuel power station, most of their key core technologies still need to be imported.

2. The customer's willingness to purchase domestic products is not strong. The performance parameters of domestic pump valve products are similar to those of foreign countries, but some customers are still willing to purchase foreign technical equipment, making it more difficult for the first domestically produced pump product with major technical equipment to enter the market. Some user departments still lack operational performance and other reasons, resulting in many domestic high-end pump products having a considerable technical level.

3. Insufficient investment in research and development of pump valve products. Compared with foreign countries, there is a significant shortage of investment in the technological development of some pump valve products, and the insufficient investment in research and development funds restricts the development of enterprise research and development technology. According to relevant data, the research and development funds in the water pump industry account for less than 2% of the company's main revenue. However, foreign research and development funds account for the majority of the proportion.
