description

KM30.27L3-83S3-LMB/MC-N-*GC external gear fan motor serves as cooling fan drive unit for Zoomlion ZE550 excavator, powered by matched hydraulic fan pump. It converts hydraulic pressure energy into rotary mechanical power to drive cooling fan. Hardened precision gear pair maintains steady torque output within wide flow range. During medium-load mining excavation, the motor speeds up fan rotation to enhance heat dissipation; under standby or light-load travel condition, fan speed automatically decreases to cut power consumption and reduce fuel consumption.
Alloy steel gear pair adopts surface hardening treatment, improving wear resistance when hydraulic oil contains tiny solid particles. High-strength cast iron housing undergoes stress relief annealing to eliminate casting residual stress, resisting thermal cycling and vibration impact generated by mining excavation.High-performance FKM fluorine rubber sealing assembly provides excellent high temperature resistance and anti-aging performance, reducing internal volumetric leakage and external oil seepage. Every fan motor passes full hydraulic bench inspection before shipment, including torque stability, speed regulation and thermal endurance test.

advantage

- Compact 27cc small-medium displacement design, perfect thermal matching for ZE550 medium mining load
27cc compact displacement realizes energy-saving torque output, precisely matching ZE550 medium-load excavation heat demand, avoiding unnecessary power waste and reducing fuel consumption.
- Built-in *GC integrated pressure protection module for stable pressure control
Integrated GC valve assembly provides pressure overload protection and pressure holding function, effectively suppressing transient pressure spikes during cyclic digging and swing, protecting internal gear and bearing components.
- Optimized low-noise gear profile reduces meshing vibration
Fine-tuned gear tooth profile reduces flow pulsation and meshing noise, lowering vibration transfer to radiator core and hydraulic pipelines, improving long-term reliability of cooling circuit.
- Lightweight reinforced housing structure, high strength with smaller installation space
Compact reinforced cast housing saves installation space in ZE550 engine compartment while maintaining structural rigidity, resisting thermal deformation under continuous medium load.
- Standard mounting interface, easy on-site replacement and maintenance
Standard flange and oil port layout matches original mounting holes, no modification required during replacement, greatly shortening machine downtime for repair.

FAQ 

Q1: Which machine does KM30.27L3-83S3-LMB/MC-N-*GC fan motor fit?
A1: This hydraulic fan motor fits Zoomlion ZE550 excavator. Confirm machine serial number before purchase.

Q2: What hydraulic function does this fan motor support?
A2: It provides rotary power for radiator cooling system, dynamically adjusting fan speed to control engine water temperature and hydraulic oil temperature, used for medium-scale mine exploitation, earth stripping and heavy excavation projects.

Q3: What are typical failure symptoms of worn fan motor?
A3: Typical symptoms: insufficient fan torque under continuous medium-load digging, slow fan speed response when temperature rises, periodic vibration during fan rotation, pressure protection function failure, gradually increased oil temperature in long shift operation, shaft seal oil seepage.

Q4: What inspections should be done before installing new fan motor?
A4: Inspect matched fan pump, cooling circuit control valve, hydraulic hoses and filter elements. Fully flush hydraulic tank and pipelines to remove metal debris. Replace degraded hydraulic oil before assembly.

Q5: What hydraulic oil should be used for this fan motor?
A5: Use ISO VG46 anti-wear hydraulic oil. Working temperature -20℃~110℃. Do not mix different oil brands, avoid long continuous running under peak pressure.
