Supplier's note

  1. Three Technical Breakthroughs:

    • The Pro Model’s 390 bar pressure rating (30% above base) enables safe operation in high-stress excavator systems.
    • Corrosion-resistant PC in the Pro Model outperforms industry-standard materials, extending service life by 40%.
    • Enhanced flow rates in Advanced/Pro Models reduce energy loss, improving system efficiency by 20%.

  2. Optimal Version Selection:

    • Base Model: Ideal for routine maintenance of standard excavator workloads.
    • Advanced Model: Recommended for mid-sized projects requiring sustained pressure handling (e.g., medium-duty digging).
    • Pro Model: Best suited for heavy-duty applications like demolition or mining, where extreme pressure and corrosion resistance are critical. With triple the corrosion protection of base models, the Pro ensures safe operation in abrasive environments.

*Note: Comparative values are relative to the Base Model’s specifications.
