Supplier's note

  1. Technical Breakthroughs:

    • Material Hardness: The Pro Model’s HT350 alloy provides 40% higher wear resistance than standard grades, extending service life by 30%.
    • Pressure Tolerance: Advanced Model’s 2400 bar rating exceeds industry benchmarks for heavy-duty diesel engines.
    • Temperature Range: The Pro Model’s +180°C limit accommodates extreme environments like mining or high-altitude operations.

  2. Version Selection Guide:

    • Base Model: Ideal for routine commercial use (e.g., long-haul trucks in moderate climates).
    • Advanced Model: Recommended for applications requiring durability in extreme cold (+/-50°C) or frequent high-load cycles.
    • Pro Model: Best suited for heavy-duty machinery (e.g., mining trucks, off-road vehicles) where peak pressure and thermal stability are critical.

With the Pro Model’s HT350 alloy, you can achieve triple the corrosion resistance of standard plungers, ensuring safe operation in corrosive fuels. Pair this with its expanded temperature range to maintain performance in arctic or desert conditions.
