Key moving parts are crafted from high-quality alloy steel and undergo specialized heat treatment, significantly enhancing gear surface hardness and wear resistance. The pump body is manufactured using a high-pressure, one-piece forming process, resulting in a compact, high-strength structure capable of withstanding peak operating pressures of up to 25 MPa.
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.
