This oil pump is manufactured under standardized specifications, designed to deliver stable lubricant delivery performance for excavators operating in heavy-duty construction and mining sites. It features premium structural durability to withstand long-hour high-load operation, with good heat resistance to adapt to temperature fluctuations during continuous mechanical movement. The precision-machined internal components ensure consistent lubricant flow to core moving parts, minimizing wear between metal friction surfaces to support extended equipment service life. Physical interception structure inside the pump effectively blocks solid debris mixed in the lubricant, maintaining flow integrity to avoid unplanned equipment downtime. It is fully aligned with factory standard installation dimensions, enabling direct replacement without additional modification, suitable for daily maintenance and overhaul of construction equipment.
