M4 Series-vane Motor

M4 Series-vane Motor Overview

The Parker M4 Series Vane Motor is a fixed-displacement hydraulic motor designed for medium- to heavy-duty applications. It converts hydraulic energy into mechanical torque and rotation through a balanced vane design, offering high starting torque, excellent volumetric efficiency, low noise, smooth low-speed performance, and reversible rotation. The modular cartridge construction allows easy maintenance and flexible displacement adjustment. Typical displacement ranges from 24.4 cm³/rev to 222 cm³/rev, with continuous working pressure up to 230 bar (≈ 3335 psi) and speeds up to about 4000 rpm, depending on the model (M4C, M4D, M4E). The M4 series is widely used in winches, cranes, marine drives, anchor machines, construction and mobile equipment, or any hydraulic systems requiring frequent direction changes and high reliability. It performs well under harsh environments and can operate with low-lubricity fluids.
