This oil pump is engineered for heavy-duty construction and mining excavation scenarios, delivering consistent lubricant supply to maintain stable engine operation during long-hour high-load work cycles. Manufactured with high-strength cast iron housing and precision-machined internal gears, it offers excellent structural durability and wear resistance, adapting to extreme temperature fluctuations from -20℃ to 120℃ without deformation. The built-in pressure regulation valve maintains steady oil pressure under variable operating conditions, minimizing risk of lubrication system instability. It is designed to meet standardized specifications, ensuring direct installation without additional modification, effectively reducing maintenance downtime for excavator fleets. The precision sealing structure provides physical blocking of external dust and debris, maintaining flow integrity of lubricating oil to extend engine service life. It is compatible with the specified engine models widely deployed in medium to large excavator equipment.
