شاحن توربيني Garrett 812905-0025 لـ حفارة Hitachi ZX330/ZX350/ZX450

Compatible Models: Isuzu 6HK1 / 6HK1-TC / 6HK1-XYSS series diesel engines.

Compatible Equipment: Hitachi ZX330/ZX350/ZX450 series excavators, Isuzu heavy-duty trucks, and industrial generator sets.

Housing Material: Constructed from high-grade, heat-resistant cast alloy with a reinforced housing structure, ensuring excellent resistance to thermal fatigue and cracking under harsh, high-temperature exhaust conditions.

Impeller Response: Features a lightweight impeller designed using precision fluid dynamics; its ultra-low inertia enables faster spool-up and transient response, significantly boosting operational power during excavation and loading tasks.

Dynamic Balancing: Every turbocharger undergoes VSR (Vibration Sorting Rig) dynamic balancing calibration across the full speed range, ensuring ultra-smooth operation and eliminating noise or oil leaks caused by high-speed vibration.

Sealing Reliability: Equipped with high-performance floating bearings and precision sealing components to effectively prevent oil leakage, maintain long-term combustion chamber cleanliness, and avoid power loss caused by carbon buildup.

Installation Fit: Fully compliant with Isuzu OEM technical specifications; flange positions and intake/exhaust port connections are precision-matched for quick, seamless, "plug-and-play" installation.
