This K7V280 hydraulic main pump is specially matched for large excavator hydraulic system. Stable heavy-load performance effectively resolve common hydraulic pump faults and reduce equipment downtime for global machinery repair shops, rental merchants and engineering contractors.
- Insufficient hydraulic output power: Internal wear leads to weak digging force under heavy load
- Pump abnormal vibration & continuous noise: Worn friction components cause shaking
- Pump overhigh oil temperature: Long-hour heavy load operation leads to sustained overheating
- Internal and external oil leakage: Aging sealing parts cause hydraulic oil spill
- Unstable flow output leads to whole machine jitter during operation
- Travel deviation, unilateral slow moving
- Insufficient climbing torque, machine slips on slopes
- Travel motor oil leakage and abnormal running noise
- Weak swing rotation torque, slow slewing with heavy bucket
- Swing jitter and friction knocking noise
- Swing shaft oil leakage, swing stuck stall
- Swing motor overheating after long continuous operation
- Control spool blocked by hydraulic impurities
- Valve body internal leakage, slow boom and bucket action
- Overflow valve pressure abnormality
