708-2L-41230、708-2L-41121 Hydraulikpumpe für Komatsu PC200-8K Bagger

Superior Responsiveness and Control: Through deep integration with the main control valve, the pump enables smooth transitions between tasks ranging from precision grading to heavy-duty excavation, ensuring excellent operator feel and rapid response.

High-Pressure Output and Energy Efficiency: The pump assembly features an advanced Pressure Cut-off function. Upon reaching the maximum pressure setting of 373 bar, the pump automatically reduces displacement to prevent system overload and excessive oil temperature rise, thereby significantly extending pump service life and reducing fuel consumption.

Mining-Grade Manufacturing Standards: The valve plate and piston assemblies are constructed from wear-resistant alloy materials, offering exceptional contamination resistance. Designed to withstand complex and variable operating environments, the pump ensures stability during high-intensity operations at a rated speed of 2,000 RPM.

Intelligent Integration: Compatible with the PC200-8K’s electronically controlled variable displacement system, the pump exchanges data with the machine's monitor (EMMS) to track operating status in real time, facilitating preventive maintenance and helping to avoid unexpected downtime.
