This hydraulic pump is a key component responsible for generating the high-pressure fluid flow required to operate the excavator's primary functions, such as boom, stick, and bucket movements. Manufactured with precision-engineered internal components and robust seals, it ensures reliable performance under demanding conditions. A worn or failed pump will result in significantly reduced lifting capacity, slow or unresponsive hydraulic controls, and potential overheating of the hydraulic system.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A failing hydraulic pump may initially manifest as a decrease in the speed and power of hydraulic functions, such as slower boom or bucket movements. If ignored, this can escalate to erratic control responses, audible whining or grinding noises, and potential hydraulic system overheating. Continued operation risks severe damage to other critical hydraulic components.
Before installing, ensure the hydraulic system is thoroughly flushed and all lines are cleaned to prevent contamination of the new pump. Never operate the new pump without first priming it and ensuring adequate hydraulic fluid levels.
When replacing the main hydraulic pump, it is essential to inspect the hydraulic fluid reservoir, replace the hydraulic filter, and check the condition of all hydraulic hoses and fittings.
