Supplier's note

  1. Technical Breakthroughs:

    • Material Upgrade: The Pro Model’s nickel-plated finish offers 50% longer corrosion resistance than standard models.
    • Pressure Tolerance: The Pro Model’s 400 bar rating exceeds industry benchmarks by 14%, enabling use in ultra-high-pressure systems.
    • Temperature Range: The Advanced Model’s expanded -30°C to 100°C range accommodates extreme environments like Arctic drilling sites.

  2. Version Selection Guide:

    • Base Model: Ideal for standard excavator maintenance where moderate pressure (≤350 bar) and temperate climates are the norm.
    • Advanced Model: Suitable for heavy-duty mining or construction in extreme temperatures, paired with its E-coating for harsh chemical exposure.
    • Pro Model: Best for high-pressure applications (e.g., demolition hammers) requiring corrosion resistance and sub-zero/ultra-high-heat resilience.

With the Pro Model’s 400 bar capacity, you can safely handle hydraulic systems in quarry operations where pressure spikes are common. Its nickel-plated surface ensures longevity even in saltwater environments. Pair the Advanced Model’s expanded temp range with Arctic-grade lubricants to maintain fluid efficiency in freezing conditions.
