Product Descriptio

This is an OEM-replacement main hydraulic pump designed for Hyundai R360LC-9 and R380LC-9 large excavators. It features an integrated dual-section variable displacement piston pump structure, incorporating a dual-power regulator, proportional solenoid valves, and a servo control valve assembly.

1. The pump body is cast as a single unit from thickened, high-strength ductile iron. Internal components—including pistons, valve plates, and retainer plates—undergo hardening treatments for wear resistance, ensuring low volumetric loss under high-pressure conditions and superior resistance to internal leakage.

2. It precisely matches the original machine's electronic power control curves, ensuring smooth response during complex operations such as heavy-duty excavation, rock breaking, and earthmoving/loading, without issues like engine stalling or RPM drops.

3. Engineered for heavy-duty mining and infrastructure applications, it features OEM-standard flanges, oil ports, and mounting dimensions, allowing for direct installation without modifying existing piping or wiring. Each unit undergoes comprehensive factory testing for pressure, flow rate, and noise levels.
