• **Compact heavy-duty gear pump custom-made for Volvo EC290B, perfectly matched with its original fan motor**
14524187 hydraulic gear fan pump is tailor-made for Volvo EC290B excavator. It cooperates seamlessly with the original fan motor. It provides stable hydraulic flow to drive cooling fan, efficiently dissipating heat during continuous operation and preventing overheating during long-time excavation tasks.
• **Rugged ductile iron housing with stress relief treatment, excellent vibration resistance**
Ductile iron shell with stress relief annealing eliminates internal residual stress. It can withstand frequent vibration and impact in earthmoving sites. The housing is resistant to deformation, slowing down wear of internal gears and bearings and extending service life.
• **Upgraded FKM sealing assembly and optimized flow path, good anti-cavitation performance**
Redesigned internal flow channel reduces oil turbulence and cavitation risk. FKM seals have outstanding high-temperature and ageing resistance. It can tolerate minor impurities in hydraulic oil and effectively avoid particle jamming, abnormal noise and premature part wear to reduce downtime.
• **Stable hydraulic power supply to protect engine and radiator from thermal overload**
This fixed displacement gear pump provides steady hydraulic power for cooling circuit. It maintains engine and hydraulic components within proper working temperature range, preventing thermal fatigue damage of radiator and engine caused by overheating, ideal replacement for EC290B overhaul and daily maintenance.

FAQ 

Q1: Can this 14524187 fan pump fit EC290 or EC290C models?
A1: This fan pump is engineered for Volvo EC290B. The mounting hole layout and shaft size are different from EC290 and EC290C. It cannot be directly installed on other EC290 series variants. Please confirm machine model and serial number before ordering.

Q2: What precautions should I take during pump replacement?
A2: Drain the old hydraulic oil and clean the hydraulic tank and pipelines before installation. Inspect the fan motor for wear or leakage at the same time. Damaged fan motor may cause overload and shorten the service life of the new fan pump.

Q3: What may lead to fast wear of the gear pair in this fan pump?
A3: The main cause is heavily contaminated hydraulic oil containing solid particles. High temperature operation for a long time and insufficient oil supply will also accelerate gear wear. Such damage is not covered by warranty.

Q4: Does this fan pump come with gaskets and O-rings in the package?
A4: The package includes a set of installation gaskets and O-ring seals as accessories. If you need extra spare seal kits for future maintenance, you can add them to your order.
