Product Description

This dual-pump hydraulic gear pump is a high-performance hydraulic power component specifically designed for heavy construction machinery such as loaders and excavators. As the power source of the hydraulic system, it relies on the rotation of a pair of precisely meshed gears to generate volume changes, continuously outputting stable high-pressure hydraulic oil, and delivering power to the lifting, steering, and moving mechanisms of the entire machine.

The pump body is made by casting a high-strength ductile iron as a whole. The castings undergo aging stress-relieving treatment, which makes them strong and resistant to impact. They can withstand continuous high pressure and the intense vibrations caused by equipment operation, and are less likely to deform or crack. The internal gears are made of special alloy steel and processed through precise grinding and quenching hardening techniques. The tooth shape is highly accurate, the meshing clearance is precisely controlled, effectively reducing operating noise and internal leakage, and having excellent wear resistance. The wear is slow even under long-term continuous operation.

The end face distribution structure is combined with high-quality sealing components, which are resistant to high pressure and aging, effectively reducing hydraulic oil leakage, ensuring stable output pressure. Even when operating in harsh environments such as high temperatures, dust, and oil contamination on construction sites, it still maintains a reliable working state. The pump shaft is treated by quenching and surface hardening, with strong torque-bearing capacity. It is combined with high-precision bearings, rotates smoothly, reduces friction loss, and extends the overall machine's service life.
