• **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.
• **Precise cooling regulation to protect whole machine**
Proportional control realizes intelligent cooling adjustment. 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 Volvo EC460 overhaul and daily maintenance.

FAQ 

**Q1: Which excavator model is this fan pump suitable for? Is it universal?**
A1: This 14561971 / 14561970 / 14405225 fan pump is specially designed for **Volvo EC460 excavator**, applied for independent proportional cooling hydraulic system. It cannot be universally used for other excavator models. Must be matched with the corresponding 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 14561971 / 14561970 / 14405225 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: Does it need professional debugging after installation?**
A3: Standard dimension, direct replacement without modification. After installation, bleed air from cooling hydraulic circuit and check pump rotation direction. If machine is still overheating, check hydraulic oil cleanliness and proportional control signal.

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