Engineered for heavy-duty construction and mining operation scenarios, this oil pump delivers consistent lubrication support for excavator and wheel loader power systems. Manufactured to factory standard specifications, it features high-strength cast iron construction with exceptional structural durability, withstanding long-term high-frequency vibration and operating temperatures ranging from -30°C to 120°C without deformation. The precision-machined internal components maintain stable oil pressure across all load conditions, minimizing unnecessary wear of moving engine parts during continuous operation. Each unit undergoes strict pressure and leakage testing before leaving the production line to ensure reliable performance under harsh job site conditions. The installation interface matches the original equipment size perfectly, allowing for direct replacement without additional modification, effectively reducing equipment downtime during maintenance.
