As the "heart" of the hydraulic system in construction machinery, gear pumps play a crucial role in power transmission. Their performance directly affects the operational efficiency, energy consumption, and stability of the equipment, and they are widely used in various construction machinery such as excavators, loaders, and cranes. For a long time, the gear pump industry in China has presented a "pyramid" competitive pattern, with abundant capacity for mid-to-low-end products, but the core technologies of high-end products have been monopolized by foreign brands, and the import dependence of ultra-high pressure and extreme working condition products was once relatively high. In recent years, with the continuous empowerment of policies such as the "14th Five-Year Plan for Intelligent Manufacturing Development", and the increasing demand for high-precision and high-reliability products from the downstream construction machinery industry, local enterprises such as Qingzhou Jiahe Hydraulic Technology Co., Ltd. have increased their R&D investment, accelerated technological breakthroughs, and promoted the structural upgrading of the industry.

Industry experts say that China's gear pump industry for construction machinery has entered a critical period of high-quality development. Favorable policies, technological innovation and market demand have combined to drive the industry's transformation from scale expansion to quality and efficiency. In the future, as domestic enterprises continue to deepen the integration of industry, academia and research for collaborative innovation, focus on core technology breakthroughs, optimize product structures and expand new application scenarios, domestic gear pumps for construction machinery are expected to further break international technological monopolies, enhance global market competitiveness and provide a more solid support for the independent and controllable development of China's construction machinery industry.
