Product Description

The hydraulic main pump is the core power assembly of the entire hydraulic system of the 7-8 ton class tailless small excavator. All the hydraulic power of the entire machine is output by this pump, providing high-pressure hydraulic oil to all the executive mechanisms such as the boom, bucket arm, bucket, rotation, and movement. The digging force, action response speed, and coordination of compound actions of the excavator are all directly determined by the working performance of this hydraulic pump. 

The pump body shell is formed by a single piece of high-strength cast steel. The shell structure is compact and thick, perfectly adapting to the limited pump chamber space of the tailless excavator. The shell has strong rigidity and can withstand continuous vibration on the construction site and the impact of peak hydraulic pressure, reducing the risks of shell deformation, oil channel cracking, and oil leakage. The entire set of sealing oil seal components uses high-performance sealing materials that are resistant to high pressure and aging caused by high and low temperatures. The multi-layer sealing protection design ensures stable sealing effect even during long-term continuous shift operations in hot summer or cold and humid environments. It can prevent oil leakage at the pump body joint and at the main shaft end, block the invasion of mud, water, and dust into the pump chamber to damage the internal precision parts, thereby extending the overall service life of the hydraulic pump from the hardware perspective, reducing downtime and economic losses caused by maintenance of small excavators.
