• **Custom fit for LiuGong CLG920 & proportional flow control**
LiuGong920 variable piston fan pump, perfectly matched for LiuGong CLG920 excavator cooling system. Works seamlessly with supporting CLG920 fan motor. Output flow automatically changes responding to engine temperature signal to match heat load, effectively solving overheating under heavy-load working conditions.
• **Stable pressure & rapid response, low leakage**
Precision ground piston, valve plate and swash plate assembly. Optimized clearance and sealing structure. Stable pressure output under fluctuating load. Maintains low volumetric leakage, preventing insufficient fan speed caused by insufficient hydraulic supply.
• **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 job sites. Less shell deformation and slower wear of internal components for longer service life.
• **Good anti-pollution & anti-cavitation performance**
Optimized suction and discharge flow path reduces oil turbulence and cavitation risk. Tolerates slightly contaminated hydraulic oil on 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 pump suitable for? Is it universal?**
A1: This LiuGong920 fan pump is specially designed for **LiuGong CLG920 excavator**, applied for independent proportional cooling hydraulic system. It cannot be universally used for other excavator models. Must be matched with CLG920 fan motor. Wrong model will lead to insufficient fan speed and machine overheating.

**Q2: What factory tests have been done for this pump?**
A2: All LiuGong920 fan pumps are 100% inspected on professional hydraulic test bench, including flow test, pressure 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.
