مضخة هيدروليكية Volvo VOE17201756 K3VL45-1NL لـ جرافة ذات عجلات Volvo L180

The VOE17201756 serves as the "power heart" driving the high-efficiency operation of Volvo excavators. It utilizes an advanced Negative Flow Control system that automatically adjusts pump displacement based on control lever input signals, ensuring optimal power output across diverse operating conditions.

Superior Load Response: The pump assembly demonstrates exceptional stability under high-pressure conditions (350 bar). Through the precise coordination of its internal servo mechanism, it enables smooth starts and rapid swing movements during heavy-duty excavation.

Energy-Saving Logic: Integrated with Volvo’s ECO mode, the pump automatically matches flow rates to engine speed, minimizing overflow losses and fuel consumption while simultaneously reducing heat generation within the hydraulic system.

Durable Design: Engineered for demanding construction and quarrying environments, the pump’s critical internal friction components feature a special hardened coating. This significantly enhances resilience against hydraulic fluid contamination and substantially extends the unit's service life.
