Supplier's note

  1. Technical Breakthroughs:

    • High-Pressure Tolerance: The Pro Model’s 455 bar rating exceeds industry standards by 20%, enabling use in ultra-heavy machinery like mining drills.
    • Adaptive Displacement: Variable flow control (up to 1,200 Nm torque) allows seamless operation in mixed-load scenarios.
    • Low Noise Design: The Pro Model’s 77 dB(A) noise level reduces environmental impact in urban construction sites.

  2. Version Selection Guide:

    • Base Model: Suitable for standard industrial applications (e.g., light to medium-duty conveyors) where cost efficiency is prioritized.
    • Advanced Model: Ideal for mid-range machinery (e.g., agricultural equipment) requiring balanced performance and noise reduction.
    • Pro Model: Recommended for heavy-duty sectors (e.g., mining, offshore drilling) where extreme pressure and silent operation are critical.
