advantage

- 48cc medium-large displacement design, customized thermal matching for LG650 heavy mining load
Medium-large 48cc displacement provides sufficient flow supply to meet the high heat dissipation requirement of LG650 under continuous rock excavation, balancing cooling performance and power consumption.
- Built-in N-CSC pressure control module for stable pressure regulation
Integrated N-CSC control module realizes pressure stabilization and overload protection, effectively suppressing pressure spikes generated by rock impact loads and protecting downstream fan motor and pipeline components.
- Optimized gear contact profile reduces meshing noise and pulsation
Modified gear contact surface reduces flow ripple and meshing noise, lowering vibration transmission to radiator and hoses, improving the stability of the whole cooling circuit under long continuous mining work.
- Reinforced heavy-duty bearing system for high pressure cyclic working conditions
Upgraded heavy-duty bearing assembly withstands repeated high-pressure cycles, reducing bearing wear and extending service life under frequent impact pressure peaks in mine sites.
- Standard flange and port layout matching original LG650 mounting interface
The mounting flange and oil port positions fully match the original machine, no modification required during replacement, shortening machine downtime and reducing on-site installation risk.
- LG650 heavy mining cyclic load bench test for reliability verification
Each pump undergoes cyclic thermal load bench test simulating LG650 continuous rock excavation working conditions to verify long-term operational stability.

FAQ

Q1: Which machine does KP30.48D0-A8K9-LMD/MC-N-CSC fan pump fit?
A1: This hydraulic fan pump fits Lingong LG650 excavator. Confirm machine serial number before purchase.

Q2: What hydraulic function does this fan pump support?
A2: It supplies regulated hydraulic flow to cooling fan motor, dynamically adjusting fan speed to control engine coolant and hydraulic oil temperature, applied for large mine exploitation, hard rock excavation and heavy earthmoving projects.

Q3: What are typical failure symptoms of worn fan pump?
A3: Typical symptoms: insufficient flow output under heavy rock digging, slow fan speed rise under high heat load, obvious pressure fluctuation during impact excavation, abnormal gear meshing noise, sustained high hydraulic oil temperature during long mining operation, shaft seal oil leakage.

Q4: What inspections should be done before installing new fan pump?
A4: Inspect matched fan motor, cooling circuit control valve, hydraulic hoses and filter elements. Fully flush hydraulic tank and pipelines to remove metal debris. Replace degraded hydraulic oil before assembly.

Q5: Why excavator still overheats after fan pump replacement?
A5: The fault may not come from pump. Check relief valve calibration, stuck valve spool, clogged filter, damaged seals or trapped air inside hydraulic circuit. Air bleeding must be completed after installation.
