Product Description

Nachi PVD Series High-Pressure Hydraulic Main Pump for Mini Excavators

Product Overview: The Nachi PVD series is the premier power core for mini excavator hydraulic systems. As a highly integrated axial piston variable displacement pump, it combines dual variable piston pumps and auxiliary gear pumps within a single compact housing. Flagship models such as PVD-2B-44P-12G-4713H (44cc) and PVD-15B-32BP-9AG5-4634G (32cc) are specifically engineered for 2.5 to 4-ton class machines. This series delivers exceptional power density and smooth displacement response, ensuring balanced power distribution during travel, swing, and bucket operations.

Key Technical Advantages:

  • Efficient Split-Power Control: Features advanced constant power regulation that modulates displacement instantly based on workload, preventing engine stalling and maximizing fuel economy.

  • Highly Integrated & Compact Design: Houses the main pump, pilot pump, and charge functions in one unit, significantly saving installation space in narrow engine compartments.

  • Wear-Resistant High-Pressure Components:

    • 4713H / 4634G Specs: Critical rotating groups (pistons, cylinders, and valve plates) are induction-hardened to withstand high-frequency pressure spikes from hydraulic breaker tasks.

  • 100% OEM-Standard Drop-in Fit: Manufactured to strict Nachi factory specifications for spline shafts, mounting flanges, and porting layouts, ensuring a seamless “plug-and-play” installation.

  • Superior Cold-Start Performance: Optimized internal fluid paths ensure responsive operations even in freezing job site environments.

Detailed Models & Parameters:

  • Core Series: Nachi PVD Series (2B, 15B).

  • Representative Models: PVD-2B-44P-12G-4713H, PVD-15B-32BP-9AG5-4634G.

  • Displacement Specs: 32 cm³/rev, 44 cm³/rev.

  • Pressure Ratings: Piston section rated at 21-25 MPa; Gear pump section at 20.6 MPa.

  • Target Equipment: Kubota, Yanmar, Komatsu, Doosan, and Takeuchi mini excavators.
