This oil pump is manufactured in line with standardized specifications, providing steady hydraulic support for excavator operations in mining and construction sites. The high-strength cast iron structure delivers excellent structural durability, resisting deformation under long-term high-pressure operating conditions. Optimized internal flow channel design maintains flow integrity of lubricating oil, effectively reducing wear between moving components during continuous operation. The high-temperature resistant sealing structure performs stably under -30°C to 120°C working environments, avoiding leakage caused by temperature fluctuations. Physical interception of metal debris in the lubrication circuit extends the service cycle of engine core components, supporting the stable operation of heavy machinery under full load working conditions for a long time. The product matches factory standard installation dimensions, requiring no modification during replacement, effectively shortening equipment maintenance downtime.
