Product Descriptio

This is the hydraulic main pump assembly for Komatsu PC200-3 and PC200-5 excavators, compatible with classic 20-ton Komatsu models. It adopts the original factory dual variable displacement piston pump structure, with the pump body, valve block, servo regulator, and mounting flange all replicating the original dimensions. No modification is required; it can be directly installed and replaced.

1. Equipped with a classic load-sensing variable displacement control system, it can adjust the output flow in real time according to the excavation load. It provides strong power for heavy-duty excavation and smooth operation for light-duty leveling, effectively solving common hydraulic problems in older excavators such as stalling, weak operation when warmed up, jamming during complex movements, and deviation during travel.

2. The internal plunger and distribution plate are made of high wear-resistant alloy material, paired with high and low temperature resistant fluororubber oil seals, reducing the risk of internal and external leakage during long-term high-temperature operation. Suitable for various engineering scenarios such as earthwork excavation, site leveling, demolition, and municipal renovation.

3. The core friction pair is precision ground, resulting in high volumetric efficiency and no significant pressure decay during long-term continuous operation. It is compatible with various hydraulic attachments such as hydraulic breakers and log grapples, ensuring durability and stability during high-intensity construction work. It completely eliminates the problems of boom drop and sluggish movement caused by hydraulic aging in older models.
