Parker Denison M5B M5A Fan Motor | M5BF045 M5AF018 | Hydraulic Vane Motor

Parker Denison M5A & M5B Series Heavy-Duty Fan Drive Vane Motors

Product Overview: The Parker Denison M5 Series is a fixed displacement vane motor family specifically engineered for the rigorous cooling systems of modern mobile machinery. This series encompasses the compact M5AF (18cc) and the high-torque M5BF (45cc). This category features flagship models: M5BF0452N04B1M00000, M5BF0451N02B1M3, and M5AF0182R04B1W00000. Utilizing a unique hydraulically balanced vane design, these motors maintain superior mechanical efficiency under extreme pressure and speed, serving as the premier power source for excavator fan systems, forestry cooling circuits, and high-performance Hydraulic Power Units (HPUs).

Key Technical Advantages:

• Elite High-Pressure Capability: Handles continuous operating pressures up to 320 Bar (4650 PSI), enhancing energy transmission efficiency and reducing system heat generation.

• Optimized High-Speed Stability: Supports continuous speeds up to 4000 RPM, ensuring cooling fans deliver maximum airflow even in the most severe ambient temperatures.

• Superior Cold-Start Performance: Optimized vane-tip sealing ensures smooth breakout performance across various temperature ranges, eliminating pressure pulsations.

• Vibration & Shock Resilience: Built for the harsh environments of mobile equipment, offering exceptional physical shock resistance and extended service intervals.

• Technical Spec Decoding:

  • M5AF / M5BF: Denotes frame size (M5A for compact frame, M5B for high-torque frame).

  • 012 / 018 / 045: Displacement codes correlating to specific cc/rev parameters.

  • 1N / 2N / 2R: Relates to rotation direction and specific shaft/porting configurations.
