Product Descriptio

This main hydraulic pump is a core power assembly component for the XE135, XE135B, SY135, and SY150 medium-sized excavators. It is developed and manufactured strictly in accordance with the original factory hydraulic system parameters. The installation flange size, output spline shaft specification, oil port position, and regulator assembly interface all match those of the original pump exactly. The entire machine can be directly replaced without modifying the original piping, supports, and control system of the excavator. It can perfectly integrate the hydraulic logic of the four models, ensuring the matching of power output for walking, rotation, digging, lifting, and compound actions. Whether it is for major equipment overhaul or emergency repair of old pumps, the assembly operation can be completed quickly, significantly reducing the time for on-site maintenance and debugging. 

The pump body shell is formed by a single piece of high-strength ductile iron casting, with excellent shock resistance and pressure-bearing capacity. In the face of complex working conditions such as earth excavation, gravel crushing operations, and heavy-load impacts on the construction site, the shell is less likely to deform or crack. The internal piston components, sliding shoes, flow distribution plate, cylinder, variable piston, and other core friction pairs are all made of high-maintenance alloy materials. They undergo multiple precise processing procedures such as quenching, precision grinding, and matching repair to effectively resist wear caused by impurities in the hydraulic oil and reduce the leakage rate inside the pump. This improves the overall service life of the hydraulic pump at the hardware level and addresses the industry pain point of premature wear of the hydraulic pump in medium-sized excavators under frequent operation.
