Product Descriptio

This main hydraulic pump for PC200-6, PC210-6, PC220-6, and PC230-6 excavators is a core component of the hydraulic powertrain for the -6 series models. As the power source of the entire hydraulic system, it directly controls all the power output for digging, lifting, rotation, movement, and compound linkage actions. It is widely applicable to various high-intensity construction scenarios such as earthwork engineering, mining, infrastructure renovation, and demolition operations. It is a key replacement assembly for major overhauls and refurbishments of old Komatsu -6 series equipment, as well as for replacing damaged pumps and storing spare parts.

The pump body shell is manufactured using a high-strength cast steel one-piece casting process, providing a sturdy and shock-resistant overall structure. It can withstand vibrations and external impacts from construction sites. The internal core moving components include the cylinder body, piston assembly, flow distributor, swing assembly, servo regulator, and other key parts. All of these are made of high-hardness wear-resistant alloy materials, processed through multiple steps such as quenching and precise grinding to enhance wear resistance and pressure resistance, effectively resisting long-term high-pressure impacts in the system, and significantly reducing common internal wear problems such as cylinder body scratching, piston wear, and flow distributor wear. Precise control of the clearance between the flow distributors significantly reduces internal leakage loss, ensuring stable output of hydraulic pump flow and pressure, and fundamentally improving problems such as weak operation, slow movement, compound action stalling, and engine stalling and speed drop in the entire machine, as well as abnormal increase in hydraulic oil temperature. The variable servo mechanism has been professionally calibrated and adjusted, with sensitive and rapid load sensing response, capable of automatically adjusting output flow and working pressure in real time according to the operating load. During heavy-load excavation operations, it provides sufficient high-pressure power, while in light-load operation conditions, it reasonably reduces power consumption, alleviating engine stalling and speed drop, and balancing the power performance of the excavator operation and fuel consumption. This significantly restores the operating feel of the old equipment, approaching the control experience of a new machine.
