Product Description

This industrial-grade high-pressure common rail injection pump is built for heavy-load commercial vehicles and mainstream excavators, featuring zero-delay response under extreme working conditions. After installation, the engine delivers crisp and quick startup, and the machine generates full, sustained power during heavy excavation or loaded climbing. It eliminates weak power output while delivering impressively low-noise and smooth operation.

Product Advantages

1. Integrated high-performance electronic metering system instantly adjusts rail fuel pressure according to real-time engine operating conditions, optimizes in-cylinder fuel spray geometry, generates strong torque and cuts fuel consumption remarkably.

2. Core precision components are upgraded via ultra-microcrystallization heat treatment and special wear-resistant coating, greatly improving tolerance to low-lubricity diesel fuel to avoid premature pump core seizure, perfectly adapting to dusty construction sites.

3. Mass-produced with high precision in strict accordance with OEM drawings, compatible with all upgraded alternative part numbers. Electrical connectors and fuel inlet & outlet bolt holes are 1:1 perfectly matched for time-saving and effortless replacement.
