Product Descriptio

This main hydraulic pump is specifically designed for the ECR88, EC80, and EC80D medium and small-sized excavators. It is the core power component that fully conforms to the original factory's main hydraulic system installation dimensions, oil port layout, and 14-tooth spline output shaft structure. The entire machine can be directly replaced and assembled without the need for additional modifications or adjustments to the excavator's pipelines, brackets, and regulator connection structures. It perfectly adapts to the overall hydraulic control logic of the three models, ensuring consistent power output for digging, rotation, movement, and compound actions of the entire machine. 

The pump body is made of a high-strength ductile iron integral casting shell. The internal pistons, sliding shoes, flow distribution plates, variable pistons, and other core friction components are all precisely machined from high-maintenance alloy materials. After undergoing multiple processes such as quenching and grinding, it effectively resists wear caused by hydraulic oil impurities in harsh conditions such as sandstone construction sites, earthwork excavation, and municipal crushing, significantly extending the overall service life of the pump body and reducing the probability of early damage under frequent operation.
