This is a high-performance hydraulic pump that generates the necessary flow and pressure for the main hydraulic system of Volvo excavators. It is constructed to meet stringent OEM quality and material specifications, ensuring consistent operation and longevity compared to worn units. Operators may observe reduced digging force, slow or erratic boom and bucket movements, or a general lack of hydraulic power when this pump begins to fail.
Always verify with serial number before ordering.

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.
The first indication of a failing hydraulic pump is typically a gradual loss of power and speed in the machine's functions, such as slower bucket curl or boom extension. If ignored, the pump's output will continue to decrease, leading to insufficient hydraulic pressure for demanding tasks and potential overheating of the hydraulic system. Continued operation risks severe damage to other hydraulic components due to insufficient lubrication and potential internal wear debris.
Ensure the hydraulic system is completely flushed and the reservoir is clean before installing the new pump to prevent immediate contamination. Do not overtighten the mounting bolts, as this can warp the pump housing and lead to internal seal damage.
Inspect the hydraulic system's main filter and any suction strainers for debris, and consider replacing the hydraulic fluid if it shows signs of degradation or contamination.
