• Rated Pressure: 250 kg/cm²

• Max. Working Pressure: 300 kg/cm²

• Speed Range: Synchronized with the front pump to ensure optimal system performance

• Manufacturer: Hung Rong Hydraulic Tech. Co., Ltd.

• Komatsu Equipment: Engineered for direct, precise application in large-capacity wheel loaders, specifically the WA600-1, WA600-1H, and WA600-1L models.

• System Integration: Operates as a critical multi-section hydraulic gear pump system where the first section governs the rear section speed. It integrates seamlessly into the multi-pump assembly to ensure efficient power distribution and synchronized hydraulic output across multiple circuits.

• Working Environment: Specialized for large heavy-duty machinery running under severe, heavy-load construction operations and intensive load cycles.

• Primary Application: Serves as a perfect drop-in replacement part for regular fleet maintenance schedules and equipment overhaul programs, effectively reducing system complexity while maintaining steady fluid control.

• Interchangeable: Precision-manufactured to strict Komatsu OEM-equivalent standards, delivering a perfect physical fit and matched operational performance.

• Optimized Design: The advanced multi-section tandem configuration significantly reduces overall hydraulic system complexity, eliminating potential leak and failure points.

• Precision and Flow: Combines superior pressure resilience with extreme displacement accuracy, ensuring reliable, high-integrity fluid power output even under maximum continuous pressure.
