Parker M5ASF Fixed Displacement Vane Motor

The Parker Denison M5ASF is a compact, fixed displacement vane motor designed for heavy-duty industrial and mobile applications. Part of the renowned M5A Series, it utilizes Parker’s patented dual-lip vane technology to deliver exceptional starting torque efficiency and volumetric efficiency. The M5ASF is specifically engineered to provide smooth low-speed operation and high reliability at pressures up to 230 bar.

Key Features:

Series: M5ASF (M5A Frame)
Displacement: 6.3 to 25.0 cm³/rev
Max. Pressure: 210 – 230 bar
Mounting: SAE A (2-Bolt).

Product Overview The Parker Denison M5ASF Vane Motor is a bi-directional hydraulic motor that converts hydraulic energy into rotary mechanical power. Unlike standard motors, the M5ASF features a hydraulically balanced design that eliminates radial bearing loads, ensuring a long bearing life even at high pressures. Its dual-lip vane design ensures positive contact with the cam ring, resulting in a very low torque ripple and consistent performance across a wide speed range.

Why Choose Parker M5ASF?

High Starting Efficiency: Delivers high torque immediately upon startup, making it ideal for winches and hoist drives under load.
Low Noise & Ripple: The multi-vane design minimizes flow pulsation, resulting in smooth rotation and quiet operation.
Compact Power: Provides high power density in a small SAE A frame size, perfect for space-constrained machinery.
Interchangeability: External mounting dimensions conform to SAE standards for easy replacement of existing motors.

Common Applications:

Fan Drives: Cooling systems in mobile equipment.
Winches: Marine and forestry winches.
Swing Drives: Mini-excavators and cranes.
Industrial: Conveyor belts, Mixers, and Agitators.
