• **Parker equivalent design, custom fit for LiuGong CLG950E & proportional speed regulation**
This Parker-model piston fan motor, perfectly matched for LiuGong CLG950E excavator cooling system. It works seamlessly with supporting Parker 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.
• **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.
• **Reliable cooling protection for engine and hydraulic parts**
Fixed piston structure delivers steady power for cooling fan. It keeps engine and hydraulic components operating within safe temperature range, preventing thermal damage to radiator and engine caused by overheating. It is the premium replacement part for LiuGong CLG950E overhaul and daily maintenance.

FAQ 

**Q1: Which excavator model is this fan motor suitable for? Is it universal?**
A1: This Parker model fan motor is specially designed for **LiuGong CLG950E excavator**, applied for independent proportional cooling hydraulic system. It cannot be universally used for other excavator models. Must be matched with the corresponding Parker 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 LiuGong950E Parker-style fan 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: Does it need professional debugging after installation?**
A3: 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 the matched fan pump.

**Q4: How to extend the fan motor service life?**
A4: Before installation, fully flush hydraulic pipeline and replace new hydraulic filter elements to remove dirt and particles. Inspect shaft, seal rings and mounting bracket for wear. After installation, perform no-load test run to check noise, rotation and temperature rise before putting into heavy mining operation.
