Product Description
Nachi PVD Series High-Pressure Hydraulic Main Pump for Excavators
Product Overview: The Nachi PVD series is the premier power core for mini excavator hydraulic systems worldwide. As a highly integrated axial piston variable displacement pump, it combines dual variable piston pumps and high-performance gear pumps within a single compact housing. Specifically engineered for mini excavators, featured models like the PVD-0B-18B-5-4950A and PVD-2B-50BP-18G5-5316A are widely used in Kubota, Yanmar, Komatsu, Kobelco, and Sany machines. Its superior power distribution logic ensures smooth operational transitions between travel, swing, and bucket functions.
Key Technical Advantages:
Comprehensive Range Coverage: Spanning from PVD-00B (micro) to PVD-3B (5-ton class), catering to diverse power requirements across various excavator models.
Split-Power Control Technology: Features advanced constant power regulation that adjusts displacement instantly based on load, preventing engine stalling and optimizing fuel efficiency.
Ultra-Compact Integrated Design: Houses main pump, pilot pump, and charge functions in one unit, significantly reducing installation footprint and simplifying piping in narrow engine compartments.
Wear-Resistant High-Pressure Components: Critical rotating groups (pistons, cylinders, valve plates) undergo specialized hardening to withstand hydraulic breaker shocks and intensive digging cycles.
100% OEM Standard Compatibility: Manufactured to strict factory specifications (e.g., codes 4950A, 5316A), ensuring mounting positions and spline shafts match the original equipment perfectly.
