Product Description
Parker M5BF045 & M5AF018 Hydraulic Fan Motor for ZX470 Excavators
Product Overview: The Parker (Denison) M5 Series consists of heavy-duty axial piston motors engineered for the most demanding environments. Thanks to their superior power density and shock resistance, these motors are the primary choice for the cooling fan systems of Hitachi ZX470 excavators. This page features high-precision configurations: M5BF045 1N03 B1M00000, M5BF045 WN04 B1M3, and M5AF 0182R01B1W00000. These motors maintain stable speeds under extreme temperatures and high-pressure conditions, ensuring efficient cooling for the excavator’s hydraulic system.
Key Technical Advantages:
Optimized for Fan Drives: Features excellent low-speed startup and smooth high-speed operation, perfectly matching the intelligent temperature-controlled cooling systems of large excavators.
High Pressure Stability: Designed for operating pressures exceeding 300 Bar, capable of withstanding instantaneous pressure spikes caused by frequent starts and stops.
Anti-Wear Engineering: Internal pistons and cylinder blocks undergo specialized hardening to extend service life even in contaminated oil or high-heat environments.
Configuration Flexibility:
M5BF045: 45cc/rev displacement, delivering massive torque to drive large-diameter cooling fans.
M5AF018: Compact 18cc/rev displacement, ideal for high-performance auxiliary drives or smaller fan systems.
Target Applications: Hitachi ZX470, ZX450 large excavator radiator fans, forestry machinery, and drilling rig cooling systems.
