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.

Gear pumps are the simplest and most common type in the hydraulic pump family, particularly suitable for budget-conscious applications or those with modest performance requirements. Their operation is straightforward: two meshing gears rotate within the pump housing. As the gears unmesh, they create a vacuum to draw in oil; when they remesh, they force the oil out.
Gear pumps offer distinct advantages: simple and compact structure, low manufacturing cost, tolerance to oil contamination, reliable operation, and easy maintenance. They're commonly found in small excavators or auxiliary hydraulic systems. However, gear pumps have clear limitations: significant flow and pressure fluctuations (technically called "pulsation"), higher noise levels, relatively low efficiency, and typically non-adjustable flow rates.
