This is a high-performance hydraulic main pump crucial for the operation of Volvo EC330B, EC360B, and EC360C excavators. Manufactured to meet rigorous OEM quality standards, it ensures reliable power delivery and longevity, outperforming worn or damaged units. Operators may experience a loss of main hydraulic functions, slow boom/arm/bucket movement, or a whining noise from the pump when it is nearing failure.

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 main pump will first manifest as a significant reduction in the speed and power of the excavator's primary functions. If left unaddressed, this will progress to intermittent loss of hydraulic pressure and extremely slow or non-responsive implement controls. Continued operation risks overheating the hydraulic system and potentially damaging the pump and other critical components.
Thoroughly flush the hydraulic system and replace the main hydraulic filter before installing a new pump to prevent contamination. Ensure all hydraulic lines are properly connected and free of kinks.
It is highly recommended to inspect and replace the hydraulic filter and check the hydraulic fluid for metal particles when replacing the main hydraulic pump.
