The key moving parts are made of high-quality alloy steel and undergo specialized heat treatment, significantly enhancing the surface hardness and wear resistance of the gears. The pump body is manufactured using high-pressure integral molding technology, featuring a compact structure and excellent overall rigidity. It can maintain structural stability under heavy-load impacts across all operating conditions, and is suitable for various long-term operational needs of medium and high-pressure hydraulic systems.
HYDSTAR® has reinforced the design to withstand the heavy-load, continuous operation typical of Komatsu equipment, ensuring stable performance in harsh environments—characterized by heavy dust, temperature extremes, and intense impacts—and substantially extending the overall service life of the machinery.
HYDSTAR® offers a comprehensive product portfolio covering single, double, and multiple-section pump configurations, with displacements spanning common operating ranges and rated pressures suited to everything from low-pressure auxiliary systems to high-pressure main systems.
The product line now includes replacements for mainstream Komatsu gear pump models, compatible with the full range of Komatsu equipment—such as excavators, bulldozers, dump trucks, and loaders—while also extending compatibility to industrial and agricultural machinery, including injection molding machines, die-casting machines, and high-horsepower tractors.
