This is a high-performance hydraulic pump crucial for the operation of Volvo excavators, providing the necessary fluid power for boom, stick, and bucket functions. Manufactured to meet exacting OEM standards, it offers superior durability and efficiency over a worn unit. Operators will typically observe slow or erratic movement of the excavator's workgroup, a loss of lifting capacity, or audible whining from the hydraulic system when this pump is failing.

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 on an excavator often first manifests as a noticeable decrease in the speed and power of the digging functions. If left unaddressed, this will progress to intermittent loss of hydraulic pressure, making the machine difficult to operate effectively. The ultimate risk is the inability to perform essential tasks, leading to significant downtime and potential damage to hydraulic cylinders from inconsistent pressure.
Thoroughly flush the hydraulic system with clean fluid before installing the new pump to remove any debris that could damage the new unit. Ensure the pump shaft is properly aligned with the drive coupling to prevent premature wear on the shaft or coupling.
Check the condition of the hydraulic fluid and replace the main hydraulic filter when installing a new hydraulic pump.
