This oil pump is engineered to meet standardized specifications for heavy-duty excavator operation scenarios including construction site earthworks and mining area long-term continuous operation. It delivers stable lubrication delivery performance to support normal engine operation under high load working conditions. Made with high-strength cast metal structure, it features excellent wear resistance and heat resistance to adapt to the harsh temperature fluctuations of excavator engine compartments. The precision-machined internal components ensure consistent lubricant flow to reduce friction loss between moving parts during engine operation, helping extend the service life of related engine components. It adopts dimensional design matching factory standard installation interfaces, requiring no additional modification during replacement, effectively reducing equipment maintenance downtime. The product has passed strict pressure and sealing tests before leaving the factory to ensure stable performance during long-term use.
