This oil pump is designed for heavy-duty construction and mining excavator operation scenarios, manufactured with standardized specifications to match factory standard performance requirements. It features high structural durability and excellent heat resistance, ensuring stable lubricant delivery during long hours of continuous high-load excavator operation. The precision-engineered internal structure effectively reduces abrasion between moving components, minimizing the risk of pressure loss during lubrication system operation. It supports steady operation within a wide temperature range, maintaining consistent lubrication supply for the excavator engine to reduce unnecessary maintenance frequency. The product undergoes strict dimensional accuracy testing before leaving the factory, ensuring seamless installation without additional modification, perfectly matching the installation position of the original equipment.
