Product Description

This high-pressure common rail injection pump is developed for premium agricultural machinery and compact construction machinery, featuring precise fuel control and outstanding rugged operation performance. After replacement, you will noticeably enjoy smoother engine operation and linear acceleration during farm cultivation or construction site work. Its superior atomization technology eliminates sudden engine stall and unstable power output, making daily heavy-duty labor easier and more efficient.

Product Advantages

1. Adopting the new-generation miniature electronic common rail injection system, it accurately adjusts fuel injection volume per millisecond according to load changes to optimize in-cylinder combustion and deliver high torque even at low engine speeds.

2. The core plunger assemblies inside the pump are reinforced via deep carburizing and wear-resistant coating, with excellent resistance to dry friction and impurity contamination, adapting to dusty and harsh farmland and outdoor working environments.

3. Manufactured in strict compliance with OEM dimensional standards, the sensor connectors and flange joints are digitally replicated at a 1:1 ratio. It supports non-destructive direct replacement without modification, greatly cutting downtime and maintenance costs of machinery.
