Nachi PVD Series Hydraulic Pump Group | PVD-0B-18P, PVD-2B-34-L3, PVD-00B | Mini Excavator Pump

Nachi PVD Series Hydraulic Main Pump Group for Mini Excavators

Product Overview: The Nachi PVD series pump group is the definitive power core for mini excavator hydraulic systems. Its unique integrated design, combining variable piston pumps with auxiliary gear pumps, allows a single unit to power travel, swing, and all implement functions within a compact footprint. Featured models such as the PVD-0B-18P, PVD-2B-34-L3, and PVD-00B-14P are specifically engineered for 1.0 to 2.5-ton machines. Known for its superior variable control logic, the PVD series ensures smooth multi-function operations—such as traveling while lifting the boom—making it the top choice for OEMs like Kubota, Yanmar, and Komatsu.

Key Technical Advantages:

• Highly Compact Integrated Structure: Houses dual variable piston pumps and single/dual high-performance gear pumps in one body, significantly saving space in narrow engine compartments.

• Precision Power Allocation Logic: * PVD-2B-34-L3: Features advanced constant power control, automatically modulating displacement based on load pressure to prevent engine stalling.

• Heavy-Duty Rotating Components: Hardened cylinders, pistons, and gear shafts are engineered to withstand high-frequency shock pressures during rigorous digging, extending service intervals.

• 100% OEM-Standard Compatibility: Specific configuration codes (e.g., 2210B, 5431A) are performance-matched to ensure flow curves and pressure cut-off points perfectly align with original equipment specs.

• Superior Response Speed: The displacement regulation mechanism responds instantly, eliminating lag between joystick movement and machine execution.
