• **Custom heavy-duty gear pump design exclusively for Volvo EC700 series, perfectly matched with EC700 fan motor**
14543168 hydraulic gear fan pump is tailor-made for Volvo EC700B / EC700C large excavator. It works synchronously with supporting fan motor. Steady hydraulic flow is delivered to drive cooling fan, matching heavy-load heat generation and effectively solving overheating risks under continuous heavy-duty mining conditions.
• **Low pressure pulsation & stable flow supply, minimized internal leakage**
Precision hobbed alloy steel gear pair with optimized tooth profile and clearance control. Deliver smooth flow under varying load conditions. Low volumetric leakage reduces energy loss and improves overall cooling system efficiency.
• **Optimized internal flow channel & upgraded sealing set, enhanced anti-cavitation and anti-contamination capability**
Redesigned internal flow path reduces oil turbulence and cavitation risk. FKM sealing rings feature excellent high-temperature resistance. It can tolerate hydraulic oil with minor impurity content, effectively preventing particle jamming, abnormal noise and premature component wear, minimizing machine downtime.
• **Reliable constant flow power supply to protect core engine components**
Fixed displacement gear pump supplies stable hydraulic power for cooling circuit. It keeps engine and hydraulic components operating within optimal temperature range, avoiding thermal fatigue damage to radiator and engine caused by overheating. It is the premium replacement part for Volvo EC700 overhaul and daily maintenance.

FAQ 

Q1: Which machine model does 14543168 fan pump fit? Can it be used on other Volvo excavators?
A1: Part 14543168 fan pump is specially designed for Volvo EC700B, EC700C large excavator. It belongs to the cooling hydraulic system and cannot be universally used for other excavator models. It must be paired with the corresponding EC700 fan motor. Wrong selection will lead to insufficient hydraulic supply and machine overheating.

Q2: What points need attention during installation and commissioning?
A2: Direct replacement without modification. After installation, bleed air from the cooling hydraulic circuit and confirm pump rotation direction. If the machine still overheats after startup, check the cleanliness of hydraulic oil and inspect gear pump for wear or internal leakage.

Q3: How to extend the service life of the fan pump?
A3: Thoroughly flush the hydraulic pipeline and replace new hydraulic filters before installation to remove dirt and impurities. Regularly inspect spline shaft, sealing rings and gear housing for wear. Complete no-load commissioning after installation, check abnormal noise, pressure and temperature rise, and put into heavy load operation only after everything is normal.
