Hitachi excavator parts K5V80DTP-YXSKR-9K00 ZX160W 9227147 hydraulic main pump

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.

Typical hydraulic pump issues and potential causes include:

• Insufficient output flow: Possible causes include internal wear reducing volumetric efficiency or malfunctioning variable mechanism limiting maximum displacement.

• Failure to reach pressure: May stem from improperly adjusted pressure compensation valve or severe internal leakage.

• Abnormal noise: Could indicate blocked suction lines causing cavitation or damaged rotating components like bearings.

• Overheating: May result from excessive system pressure settings or overly viscous oil increasing mechanical losses.

For these issues, consult professional technicians rather than attempting high-pressure pump repairs yourself, to avoid further damage or safety hazards.
