Product performance advantages

1. Original factory-level precision matching, direct installation in situ, no need for modification, debugging, and installation<br>2. Stable pressure output, sufficient flow supply, strong digging force, and smooth compound movement without lag<br>3. The pilot system is responsive and precise, and does not hold the vehicle back or fall off<br>4. The core components are made of high-strength wear-resistant materials, resistant to high temperatures, abrasion, and adaptability<br>5. Upgraded seals eliminate hidden dangers of oil leakage, and the hydraulic system of the entire machine operates more stably.

Highlights of cost performance

1. The quality is comparable to the original brand-new parts, the performance is up to standard, and the failure rate<br>2. The price is much lower than the original factory pump, and the procurement cost is greatly reduced.<br>3. The compatible models are single and the coverage is wide, so stocking is worry-free<br>4. The bench is fully inspected before leaving the factory, with stable performance and worry-free warranty, taking into account durability and economy.

Product core positioning

The exclusive hydraulic pump assembly specially built for Carter's 20-ton 320D series excavators integrates the original specification pilot pump and perfectly matches the original hydraulic system. It is the cost-effective first choice for excavator maintenance, overhaul and parts replacement, and fully meets the needs of high-intensity operations in multiple scenarios such as earthmoving, urban construction, and mining.
