Product Descriptio

This hydraulic main pump is a dedicated main pump assembly for SK60, SK60-3, SK60-5, and SK75 small excavators. It features an integrated composite structure of piston pump and pilot gear pump. It is the power core of the hydraulic system for these small excavator models and is widely applicable to various light to medium-intensity engineering scenarios such as urban earthwork construction, landscaping, pipeline excavation, old building demolition, small-scale infrastructure projects, and farmland renovation.

The core components inside the pump body are manufactured using precision wear-resistant alloys. The pistons, cylinder bodies, and flow distribution discs, among other key friction pairs, undergo CNC precision grinding and heat treatment processes to enhance surface hardness and improve resistance to wear and impact. This enables the pump to adapt to complex environments such as dust, mud, and temperature fluctuations on construction sites, effectively reducing internal wear and hydraulic internal leakage issues over long-term operation. The pump housing is made of high-strength cast iron through a single casting process, featuring a compact and thick structure with strong vibration resistance. It is less likely to crack or leak oil and water under frequent starting and stopping, and repeated impact conditions of small excavators. The pump is also equipped with original factory specifications regulators and high-quality sealing components, ensuring sensitive control response, stable displacement adjustment, and the ability to automatically adjust output power according to load changes. This helps balance digging force and fuel economy, effectively addressing common hydraulic faults in SK60 and SK75 series older models such as insufficient digging power, slow warm-up actions, abnormal pump noise, insufficient pressure, and rising oil temperature. It reduces downtime and maintenance costs caused by equipment shutdowns.
