200-3406 CAT325C Fan Pump for Caterpillar CAT325C 25-ton Medium Excavator spare parts

Short Description:

The Caterpillar CAT325C fan pump is an original dedicated hydraulic power pump matched for CAT325C 25-ton medium excavator. As the core power source of the independent hydraulic heat dissipation system, it replaces the traditional engine direct-drive fan structure, independently providing stable hydraulic power for the cooling fan motor. It precisely matches the temperature control logic and hydraulic system parameters of CAT325C, driving the fan to perform adaptive heat dissipation operation. Optimized for municipal construction, earthwork excavation, long-duration continuous operation and summer high-temperature working conditions, this fan pump features stable pressure output, low pulsation, strong anti-pollution performance and low failure rate, effectively solving equipment overheating problems and ensuring the whole machine maintains a constant optimal operating temperature.

description

The genuine CAT325C hydraulic fan pump adopts high-precision fixed-displacement gear pump structure, professionally calibrated for Caterpillar’s independent fan cooling system. It features compact layout, stable oil supply and low operating noise. The internal high-precision gear pair, reinforced bearing assembly and high-strength pressure-resistant sealing structure undergo strict finishing and wear-resistant strengthening treatment, ensuring continuous and stable hydraulic output under long-term cyclic load and high-temperature environment. The integral high-rigidity pump body resists construction site vibration and hydraulic impact, avoiding pressure fluctuation and insufficient fan speed caused by pump body deformation or internal component wear. All finished fan pumps pass factory full-pressure testing, flow calibration and high and low temperature cycle durability tests, with reliable overall performance and long service life, perfectly adapting to the daily high-frequency operation needs of CAT325C medium excavators.

advantages

Genuine CAT part number 200-3406, exclusively calibrated for CAT325C independent heat dissipation hydraulic system, perfectly matching the machine’s temperature control parameters, providing stable and continuous power for the fan motor and avoiding insufficient heat dissipation power.
High-precision gear pair design effectively reduces flow pulsation and internal leakage, ensuring constant fan speed, no jitter or speed drop during long-term operation.
Reinforced wear-resistant structural configuration adapts to long-term high-frequency medium-load operation, with low component wear rate and long service life.
Excellent high-temperature resistance and pressure stability, no pressure attenuation or stalling in summer high-temperature and continuous working conditions, effectively preventing equipment overheating.
Integrated compact pump body structure has strong anti-vibration capability, adapting to complex and changeable construction site environments with low failure rate.
Standard original installation size supports 1:1 non-destructive direct replacement, no modification or debugging required, greatly improving maintenance efficiency.
Independent oil supply design separates the heat dissipation hydraulic circuit from the main hydraulic system, avoiding mutual interference and improving the stability of the whole machine’s hydraulic system.

maintenance & replacement tips

Regularly inspect fan pump mounting bolts, oil inlet and outlet joints and sealing surfaces to eliminate oil leakage risks caused by long-term construction vibration and mechanical impact.
Replace dedicated hydraulic filter elements and hydraulic oil on schedule to prevent hard impurities from scratching internal gear pairs and bearings, avoiding insufficient oil supply and unstable pressure.
Clean fan blades and radiator dust and dirt regularly to prevent heat dissipation blockage, which causes long-term overload operation of the fan pump and accelerates component wear.
Periodically detect the output pressure and flow rate of the fan pump to ensure it operates within the rated range and meets the heat dissipation requirements of CAT325C.
Avoid long-term high-temperature overload operation and abnormal hydraulic pressure impact to reduce fatigue wear of internal precision components.
Timely replace genuine 200-3406 CAT325C fan pump when faults such as weak heat dissipation, fan speed instability, oil leakage and system high temperature occur to restore the equipment’s heat dissipation performance.
