Advantages of the Eaton PVH-74 Variable Displacement Piston Pump

  • High Pressure Capability: Supports continuous pressures up to ~250 bar and even higher in load-sensing mode, ensuring robust performance under demanding loads.

  • Variable Displacement Efficiency: The PVH-74 offers variable displacement control, which means you can precisely regulate flow, reducing power losses and improving fuel / energy efficiency.

  • Compact and Lightweight: Its inline piston design in a compact housing reduces weight, which is beneficial for mobile machinery where space and mass matter.

  • Flexible Control Options: Multiple control modes (pressure-compensated, torque-limited, load-sensing) provide adaptability for different hydraulic system architectures.

  • Durable Design: Built with proven Vickers/Eaton components to ensure long service life and reliability even in harsh environments.

  • Optimized for Continuous Duty: Engineered to run continuously in heavy-duty use without compromising performance, making it ideal for mobile and industrial applications.
