Product Descripti

This hydraulic main pump, which is compatible with PC150, PC200EN-6K, PC150-6K, PC160-6K, and PC180-6K excavators, is the power core assembly of the hydraulic system for this series of medium-sized excavators. The power output for all digging, lifting, rotating, moving, and compound actions of the entire machine is provided by this main pump. It is widely used in various operation scenarios such as municipal earthwork, river dredging, infrastructure excavation, construction site crushing, and landscaping. It is the core replacement part for the major modifications of the -6K series equipment, the replacement of damaged pumps, and the inventory preparation of spare parts.

The pump body shell is made of high-strength cast steel and is formed by a single casting process. The overall structure is solid and stable, with strong resistance to vibration and impact. It can adapt to the continuous vibration and external impact conditions in construction work environments. All internal core parts such as the cylinder body, piston, flow distributor plate, swing component, and servo regulator are made of high-maintenance alloy materials. They undergo multiple processing techniques such as quenching and precise grinding to enhance the hardness and wear resistance of the surface of the parts, effectively withstand the frequent high-pressure impact of the hydraulic system, significantly reduce common internal faults such as cylinder body scratching, piston wear, and flow distributor plate burnout. The clearance between the flow distributor plate is precisely controlled to effectively reduce internal leakage loss of hydraulic oil, stably maintain the output flow and system pressure of the hydraulic pump, and fundamentally improve a series of equipment problems caused by pump wear, such as insufficient digging power, slow action response, uncoordinated compound actions, engine stall and speed drop, and abnormal increase in hydraulic oil temperature. The load sensing servo regulation mechanism has been professionally calibrated and adjusted, with a sensitive variable response. It can automatically adjust the output flow and working pressure in real time according to the changes in the working load, providing sufficient high-pressure power for heavy-load operations, and reasonably reducing power consumption in light-load conditions. It alleviates engine overload and stall, balances the operation power and fuel economy, and significantly restores the operating feel of old equipment.
