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
