This oil pump is engineered for heavy-duty construction and mining excavator operation scenarios, delivering consistent lubrication support for PC300-6 excavators equipped with 6D108 and SAA6D108E engines. Manufactured to standardized specifications, it features high-strength cast iron housing and precision-machined internal gears, offering exceptional structural durability and heat resistance to handle long-term high-load operation under -20℃ to 120℃ working temperature ranges. The precision-matched seal structure realizes physical blocking of external debris intrusion, maintaining flow integrity of lubricating oil to reduce abnormal wear of engine moving parts. Each unit undergoes strict pressure and flow testing before leaving the factory to ensure installation compatibility with designated models, supporting stable operation of excavator hydraulic and power systems during earthwork, road construction and mining excavation tasks.
