Product details
I. Product Overview
The Parker M4C, M4D, M4SC, and M4SD series high-pressure vane motors belong to Parker Denison’s M3/M4 family, designed for high-load, high-efficiency hydraulic systems. Widely used in construction machinery, marine propulsion, and industrial equipment, their core advantages include:
• High starting torque: Smooth startups under heavy loads without pressure overshoot or transient power overload.
• Low-speed stability: Minimal torque ripple at low speeds (e.g., swing or load-lifting drives), ensuring stable operation.
• Long service life and high efficiency: Pressure-balanced design of vanes, rotors, and stator rings maintains high volumetric efficiency and extends lifespan.
• Compact structure: Integrated design saves installation space, adapting to diverse hydraulic system layouts.
II. Model Comparison and Specifications
【表格】
Model Displacement Range (cm³/rev) Rated Pressure (MPa) Max Speed (rpm) Typical Applications
M4C 062, 074, 088, 102 23 3600–4000 Crane winches, light construction machinery drives
M4D 088, 102, 128, 138 23 3600–4000 Excavator swing drives, marine propulsion systems
M4SC 062, 074, 088, 102 23 3600–4000 High-precision industrial equipment, light vehicle drives
M4SD 088, 102, 128, 138 23 3600–4000 Heavy construction machinery, mining equipment main drives
Key Parameter Notes:
• Displacement: Determines motor output flow; higher displacement = greater hydraulic oil volume per revolution.
• Rated Pressure: Maximum sustainable operating pressure (23 MPa for all M4 series), suitable for high-pressure applications.
• Max Speed: Maximum rotational speed under rated pressure, directly impacting system efficiency.
III. Core Advantages and Technical Features
1. High Starting Torque Efficiency
• The vane motor design delivers maximum torque instantly during startup, preventing stalling or jitter under heavy loads—ideal for cranes and winches.
2. Low-Speed Smoothness
• Minimal torque ripple at low speeds (50–500 rpm) ensures shock-free operation, extending mechanical component lifespan.
3. Pressure-Balanced Design
• Pressure-balanced vanes, rotors, and stator rings reduce internal leakage, achieving volumetric efficiency >90% while minimizing wear.
4. Compatibility and Interchangeability
• Fully interchangeable with Parker Denison original parts, the M4 series supports direct replacement of competing brands (e.g., Rexroth, Kawasaki), lowering maintenance costs.
5. Sealing and Reliability
• High-performance seals (e.g., PTFE lip seals) prevent hydraulic fluid leaks, adapting to harsh conditions (high temperatures, pressures, and dust).
IV. Typical Applications
1. Construction Machinery
• Excavators: M4D/M4SD for swing drives, providing high torque and precise control.
• Cranes: M4C/M4SC for winch drives, enabling heavy-load lifting and lowering.
• Loaders: M4 series for working device hydraulic systems, enhancing operational efficiency.
2. Marine and Offshore Engineering
• Propulsion Systems: M4D/M4SD for propeller drives, meeting high-load navigation demands.
• Deck Machinery: M4C for anchor winches and capstans, ensuring reliable operation.
3. Industrial Equipment
• Injection Molding Machines: M4SC for high-precision hydraulic power, optimizing molding cycles.
• Die-Casting Machines: M4D for clamping mechanisms, enabling rapid and stable movements.
