Hitachi Excavator ZX200-3 9262319 9262320 Hydraulic Pump Assy For Mini Excavator

Hitachi excavator ZX200-3 9262319 9262320 hydraulic pump assy for mini 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.
