مضخة هيدروليكية Doosan 32362406 لـ حفارة Doosan DH80-7

The 32362406 serves as the core hydraulic power source for the DH80-7 excavator. This pump is specifically engineered to meet the high-efficiency operational demands of 8-ton class compact excavators in applications such as urban construction, pipeline laying, and small-scale earthworks.

Load-Sensing Capability: Featuring excellent pressure compensation characteristics, the pump adjusts the tilt angle of its internal pistons in real-time based on load fluctuations in the working implements (such as the bucket and boom), thereby delivering flow precisely according to demand.

High-Efficiency, Energy-Saving Design: The unit incorporates a pressure cut-off function that effectively minimizes power loss during no-load or holding operations—a critical factor for the fuel economy of compact excavators.

Compact Structure: Designed specifically for the DH80-7’s compact engine compartment, the pump ensures sufficient displacement while simplifying piping connections to the main control valve, facilitating ease of maintenance and replacement.

Weather and Impact Resistance: Engineered to withstand the frequent operational cycling typical of small-to-medium excavators, the pump utilizes highly wear-resistant materials for its rotating assembly, ensuring stable performance output even in the harsh, dusty environments of a construction site.
