• **Custom fit for Doosan DX520 & proportional speed regulation**
A10FE28 /52L-VCF10N000 piston fan motor, perfectly matched for Doosan DX520 excavator cooling system. It works seamlessly with supporting proportional fan pump. Fan speed automatically changes with hydraulic flow to match heat load, effectively solving overheating under heavy-load mining working conditions.
• **Stable torque & quick response, low leakage**
Precision ground piston, valve plate and swash plate assembly. Optimized clearance and sealing structure. Stable torque output under back pressure. Rotates steadily with low volumetric leakage, preventing insufficient fan power caused by pressure drop.
• **Heavy-duty cast iron housing, shock & vibration resistant**
Cast iron shell treated by stress relief annealing to eliminate residual internal stress. It can withstand continuous vibration, hydraulic impact and dust corrosion on mining sites. Less shell deformation and slower wear of internal components for longer service life.
• **Good anti-pollution & anti-cavitation performance**
Optimized flow path reduces oil turbulence and cavitation risk. Tolerates slightly contaminated hydraulic oil on mining site. Effectively prevents particle jamming, abnormal noise and premature component wear, ensuring continuous stable operation and less downtime.

FAQ 

**Q1: Which excavator model is this fan motor suitable for? Is it universal?**
A1: This A10FE28 /52L-VCF10N000 fan motor is specially designed for **Doosan DX520 excavator**, applied for independent proportional cooling hydraulic system. It cannot be universally used for other excavator models. Must be matched with corresponding proportional fan pump. Wrong model will lead to insufficient fan speed and machine overheating.

**Q2: What factory tests have been done for this motor?**
A2: All A10FE28 /52L-VCF10N000 motors are 100% inspected on professional hydraulic test bench, including torque test, speed curve detection, high-low pressure tightness test and internal leakage inspection. Strict screening ensures stable field performance, test reports can be provided upon request.

**Q3: What is the warranty scope and non-warranty scope?**
A3: We provide **12-month warranty**. Warranty covers performance failure when installed correctly, using clean hydraulic oil and running under specified working conditions. Damage caused by hydraulic oil contamination, particle jamming, overpressure impact, wrong installation or man-made damage is not covered by warranty.

**Q4: Does it need professional debugging after installation?**
A4: Standard dimension, direct replacement without modification. After installation, bleed air from cooling hydraulic circuit and check fan rotation direction. If machine is still overheating, check hydraulic oil cleanliness and proportional control signal of fan pump.
