SH460 Fan Pump for Hyundai 46-ton Super-large Engineering Mining Excavator spare parts

product parameters

• Exclusively calibrated for HYUNDAI SH460 46-ton super-large excavator hydraulic heat dissipation system, perfectly matching original equipment hydraulic parameters and temperature control logic without power mismatch or poor cooling effect.
• Upgraded heavy-duty gear pump structure, with higher pressure resistance and overload capacity than ordinary fan pumps, effectively solving the long-standing problem of insufficient cooling power and high-temperature alarm of SH460 large mining excavators under extreme full-load working conditions.
• Precision matched internal gear pair and bearing assembly minimize internal leakage and flow fluctuation, ensuring stable fan speed and no jitter or speed drop during long-term high-intensity mining heavy-duty operation.
• High-temperature aging-resistant composite sealing system prevents oil leakage and performance attenuation, adapting to long-duration high-heat continuous operation of high-power engines of 46-ton super-large excavators.
• Integrated high-rigidity cast pump body has strong anti-vibration and anti-dust erosion capabilities, maintaining stable working performance in harsh mine and high-temperature construction environments with ultra-low failure rate.
• Independent oil supply circuit design separates the heat dissipation hydraulic system from the main hydraulic system, avoiding hydraulic interference, improving overall machine stability and reducing fuel consumption.
• Original standard mounting size supports 1:1 non-destructive direct replacement, no modification or complicated debugging required, effectively reducing downtime and high maintenance costs of super-large mining equipment.

• Regularly check the mounting bolts, oil inlet and outlet joints and sealing surfaces of SH460 fan pump to eliminate oil leakage risks caused by long-term mine heavy-load vibration and strong mechanical impact.
• Clean the radiator and fan blade dust, sediment and dirt regularly to avoid heat dissipation blockage, prevent long-term overload operation of the fan pump and delay internal component wear and aging.
• Replace hydraulic oil and special precision filter elements in strict accordance with Hyundai official maintenance cycle to prevent hard mine impurities from scratching precision gear pairs and ensure stable pressure and flow output of the pump body.
• Periodically detect the working pressure and flow rate of the fan pump to ensure it operates within the rated range and meets the extreme full-load heat dissipation requirements of SH460 super-large excavators.
• Avoid long-term extreme high-temperature overload operation and abnormal hydraulic impact to reduce fatigue wear of internal precision components and extend the service life of the heavy-duty fan pump.
• Timely replace genuine SH460 fan pump when faults such as weak heat dissipation, unstable fan speed, pump body oil leakage and continuous system high temperature occur to restore the extreme heavy-duty cooling performance of the equipment.
