advantage

- Fast flow response linked with temperature sensor for real-time thermal control
Quick flow adjustment responds rapidly to temperature sensor signals, dynamically adjusting fan motor speed to keep engine and hydraulic oil temperature within optimal working range.
- Optimized gear meshing profile reduces pulsation and noise under continuous operation
Refined gear tooth profile minimizes flow ripple and meshing noise, reducing vibration transfer to radiator and pipeline during long-time continuous mining work.
- Reinforced cast housing with high thermal stability for heavy-duty excavator engine bay
Stress-relieved thick cast shell maintains structural integrity under repeated thermal shock, resisting deformation in high-temperature engine compartment environment.
- Enhanced anti-scuffing gear pair reduces wear under fluctuating pressure cycles
Special anti-scuff treatment on gear contact surface lowers the risk of metal seizure under frequent pressure fluctuation caused by cyclic excavation load.
- Integrated port layout simplifies pipeline assembly and reduces vibration fatigue risk
Optimized integrated oil port arrangement shortens external pipeline length, lowering vibration fatigue and oil leakage risk in compact engine compartment.

FAQ

Q1: Which machine does KP30.31S0-A8K9-POF/OD-T-PV-HSC fan pump fit?
A1: This hydraulic fan pump fits Lovol FR485 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, controlling fan speed for engine coolant and hydraulic oil temperature management, used for mining, heavy earthmoving and large infrastructure projects.

Q3: What are typical failure symptoms of worn fan pump?
A3: Typical symptoms: insufficient flow to drive fan motor, fan cannot speed up under high temperature, flow fluctuation during load change, abnormal meshing noise, continuous oil temperature rise under heavy digging, 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.
