Belparts Excavator K5V200DPH-NXMXR-OE11 Hydraulic Pump ZX450-1 4432815 For Hitachi

Belparts excavator K5V200DPH-NXMXR-OE11 hydraulic pump ZX450-1 4432815 for Hitachi

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.

Displacement and Flow Rate: Determining Excavator "Movement Speed"

Displacement refers to the oil volume a pump can discharge per revolution, typically measured in milliliters per revolution (ml/rev). For example, a "45ml/rev" pump theoretically discharges 45ml of hydraulic oil per revolution. Flow rate indicates oil volume output per unit time, measured in liters per minute (L/min), calculated by multiplying displacement by rotational speed.

In excavators, displacement and flow rate directly affect working component movement speed. Larger displacement pumps provide greater flow, enabling faster bucket or boom movement. However, excessive displacement increases system heat and reduces efficiency. Modern variable pumps can adjust effective displacement as needed, providing "on-demand" distribution that ensures quick movements while avoiding energy waste.
