HITACHI K5V200DPH-XMXR-OE02 ZX450-3 9199338 hydraulic Pump Assembly for excavator

The hydraulic pump converts mechanical energy into hydraulic energy to power the excavator's hydraulic system. When the engine drives the pump shaft to rotate, the internal pistons or gear sets create oil suction and compression processes, forming a high-pressure oil flow. Belparts hydraulic pumps feature variable displacement design that automatically adjusts output flow according to load requirements, achieving high energy efficiency.

List of spare parts

When you see an excavator effortlessly lifting tons of soil or precisely moving its bucket to a designated position, the key component behind these actions is the hydraulic system, with the hydraulic pump serving as its "heart." Simply put, a hydraulic pump functions much like the human heart, continuously "pumping" hydraulic oil to various actuators of the excavator, providing powerful support for the entire machine.

The working principle of a hydraulic pump is not overly complex. Through mechanical motion (typically the engine rotating the pump shaft), it creates volume changes within the pump chamber, resulting in oil suction and discharge. When the pump chamber's volume increases, a partial vacuum forms, drawing hydraulic oil from the tank. When the volume decreases, the oil is compressed, pressure rises, and the oil is then delivered into the hydraulic system. This cyclical suction and discharge process creates a continuous flow of hydraulic oil.

In excavators, hydraulic pumps play a vital role. Without them, even the most powerful engine couldn't transfer energy to working components like the bucket or boom. The performance of a hydraulic pump directly determines an excavator's efficiency, operational smoothness, and fuel economy. A high-quality hydraulic pump enables an excavator to be both "powerful" and "energy-efficient," which is why modern excavator manufacturers place such emphasis on hydraulic pump technology.
