- Key functions
1.Auxiliary Hydraulic Power: Supplies pressurized oil to auxiliary functions like bucket tilting, arm retraction, or hydraulic hammer attachments (for breaking rock/concrete) in excavators.
2.Consistent Flow Delivery: Its positive-displacement design ensures a fixed oil flow rate at a given engine speed, preventing fluctuations in hydraulic power that could cause jerky or unresponsive machine movements.
3.Compact Integration: The aluminum housing and small footprint allow it to fit in tight spaces within the machine’s engine compartment—critical for Komatsu’s compact excavator/loader designs.
4.Low Maintenance: With fewer moving parts than piston pumps, it requires minimal upkeep (e.g., only regular oil changes) and has a longer service life under normal operating conditions.
