Product Description

Nachi PVD Series Main Hydraulic Pump for Mini Excavators

Product Overview: The Nachi PVD series is the world-leading hydraulic pump solution for the mini excavator market. Featuring a unique integrated twin or triple pump design, it combines two axial piston units and one gear pump (or three piston groups) within an extremely compact housing. Specifically engineered for 1 to 6-ton excavators, the PVD series ensures precise synchronization and high efficiency for travel, swing, and boom operations through its superior variable displacement control logic.

Key Technical Advantages:

  • Highly Integrated Architecture: The PVD series (e.g., PVD-2B-50) consolidates multiple hydraulic circuits into a single unit, maximizing space efficiency within the limited engine compartments of compact machinery.

  • Precise Variable Modulation (L3PS / 3DPS): * Incorporates advanced Load Sensing and total power control technology, automatically adjusting displacement based on load pressure to prevent engine stalls.

    • Models like PVD-2B-41BP utilize precision internal valving for seamless compound movement switching.

  • Durability & Shock Resistance: Designed for harsh construction environments, featuring reinforced bearings and rotating components to maintain stable output under continuous high pressure and intense shock loads.

  • Broad OEM Compatibility: The PVD series is the standard OEM pump for globally renowned mini excavator brands, including Kubota, Takeuchi, IHI, and more.

Detailed Models & Technical Parameters:

  • Core Models: PVD-1B, PVD-2B, PVD-3B.

  • Detailed Config Codes: PVD-2B-41BP-16G5-4713, PVD-1B-27L3PS-9G-4357F, PVD-2B-50L3DPS-21G-4439F.

  • Application Range: 1.5T, 2.5T, 3.5T, 5T class mini excavators.

  • Control Methods: L3PS (Power Regulation), 3DPS (Triple Pump Power Control), BP (Bypass Regulation).
