Supplier's note

  1. Technical Breakthroughs:

    • The Pro Model’s 390 bar pressure rating (30% above industry standards) enables stable fuel delivery in extreme temperatures.
    • Military-grade alloy construction (Pro) reduces wear by 40% compared to standard materials.
    • All models feature a 6-month warranty, extending 3x longer than typical aftermarket parts.

  2. Optimal Version Selection:

    • Base Model: Ideal for light-commercial vehicles (e.g., delivery trucks) with standard engine loads.
    • Advanced Model: Tailored for medium-duty fleets (e.g., buses) requiring enhanced durability in corrosive environments.
    • Pro Model: Designed for heavy-duty applications like mining or marine engines, where peak pressure and longevity are critical.

With the Pro Model’s 390 bar pressure, you can achieve consistent fuel flow even in high-altitude or extreme-temperature conditions. With Military-grade alloy, you can reduce downtime by minimizing wear-related failures.
