Product Descriptio

This hydraulic main pump, designed for PC200-7, PC220, and PC220-7 excavators, is the power core assembly of the entire hydraulic system. It directly determines the overall performance of the excavator in terms of digging, rotating, moving, and compound actions. It is widely used in various high-intensity operation scenarios such as earthwork excavation, mining stripping, infrastructure construction, demolition and crushing, etc. It is a core replacement part for equipment major repairs, old pump replacements, and engineering equipment renovation. This hydraulic pump strictly conforms to the original factory assembly dimensions, oil port layout, and installation flange specifications. The assembly interface perfectly matches the model, and there is no need to modify the pipelines, supports, and connection structures. The overall disassembly and replacement are convenient.

The pump body is made of high-strength cast steel and is formed by one-piece casting. The internal components such as the piston, cylinder, flow distributor, swing, and servo valve are made of wear-resistant alloy materials. They undergo precise quenching and grinding processing to be resistant to impact and high pressure. It can withstand the frequent pressure shock of the hydraulic system for a long time, effectively reducing common faults such as internal wear, scratches, and pressure relief. The precision-machined flow distributor joint has precise control of the clearance, reducing the loss of high-pressure oil inside and ensuring stable output flow of the pump body. This avoids typical problems such as slow operation, lack of power, stuck compound actions, and overheating of the vehicle during idling in the excavator. The entire servo control mechanism has been finely calibrated, with a sensitive variable response. It can automatically adjust the output flow and pressure according to the load, perfectly matching the load changes of the excavator. During heavy-load excavation, it provides sufficient pressure output, and during light-load operation, it reduces power consumption, improving engine idling and shutdown phenomena, and balancing the operation power and fuel economy. This restores the operating feel of the entire machine to the new machine level.
