Excavator Hydraulic Pump Excellence
--- Unmatched Quality and Performance ---
• Advanced Technology in Hydraulic Pump Design:
At ZHTE Hydraulic, our hydraulic pump development is rooted in cutting-edge R&D and deep industry expertise. In 2015, we successfully launched our first domestically developed excavator travel motor, which laid the foundation for our breakthrough in hydraulic pump technology. By 2016, we established Xingtai Zhongwei ZhuoTe Hydraulic Technology Co., Ltd., introducing over 200 sets of high-end production and testing equipment from Germany and Japan, including automated CNC machining centers and intelligent hydraulic test benches. This investment enabled us to achieve a level of precision and reliability previously only seen in imported brands. Our K3V112 model hydraulic pump, designed for heavy-duty applications in Sany and XCMG machines, exemplifies this excellence—delivering consistent pressure output (up to 40 MPa) and efficiency exceeding 92%, rivaling top-tier international counterparts like those from Volvo and Komatsu. A real-world case in point comes from a large-scale infrastructure project in Kazakhstan, where a fleet of 18 ZT75W-L wheeled excavators equipped with our K3V112 pumps operated continuously for over 12 months in extreme temperatures (-30°C to +45°C). Despite harsh conditions, none of the hydraulic pumps failed, and maintenance intervals were extended by 30% compared to previous models. This performance was validated through ICR conformity verification certificates (No: ICR Polka/VC/H220701 and ICR Polska/VC/H220702), confirming compliance with European safety and performance standards. Furthermore, our collaboration with Zhejiang University on hydraulic transmission research has led to proprietary internal flow optimization algorithms, reducing internal leakage by up to 25% and improving thermal stability. With more than 118 nationally authorized patents and a 200 million yuan R&D investment in 2024, ZHTE Hydraulic continues to push the boundaries of what’s possible in hydraulic pump design—proving that domestic innovation can match, and even surpass, global benchmarks.
