Product Description
Yanmar Vio17 Main Hydraulic Pump – Nachi PVD Series for Mini Excavators
Product Overview: The Nachi PVD axial piston variable displacement pump series is the definitive power core for the Yanmar Vio17 and other 1.5-2.5 ton class mini excavators. Featuring a highly integrated multi-pump design, this unit combines dual variable displacement piston pumps with a high-performance gear pump within a single housing. Featured models like the PVD-0B-16BP-6AG4 and PVD-2B-50L3DPS-21G are specifically engineered for the compact engine compartments of mini excavators. Its advanced load-sensing and smooth power distribution technology ensure that the excavator performs multi-function operations (such as traveling while lifting the boom) with precision, smoothness, and zero lag.
Key Technical Advantages:
Superior Power Matching: Optimized for Yanmar Vio series engine characteristics, featuring excellent constant power control to prevent stalling under high loads and reduce fuel consumption.
Highly Compact Integrated Structure: Combines main pump and pilot charge functions, reducing hydraulic connection points and minimizing the risk of system leakage.
Wear-Resistant High-Pressure Components: Hardened pistons, cylinders, and valve plates are engineered to withstand high-frequency shock pressures during rigorous digging, significantly extending service intervals.
100% OEM-Standard Compatibility: Manufactured to strict factory specifications (e.g., codes 4733A, 21G), ensuring that mounting positions, spline shafts, and port locations match the original equipment perfectly.
Rapid Displacement Response: Optimized servo-variable mechanisms allow the excavator to transition between heavy digging and grading in milliseconds, maximizing operational efficiency.
Detailed Models & Parameters:
Core Series: Nachi PVD Series (00B, 0B, 2B).
Representative Models: PVD-0B-16BP-6AG4, PVD-2B-50L3DPS-21G, PVD-00B-15-3-4733A.
Target Equipment: Yanmar Vio17, Vio15, Vio20, and similar tonnage mini excavators.
Pressure Ratings: Piston section rated at 21-24.5 MPa; Gear pump section rated at 20.6 MPa.
Displacements: 15, 16, 25, 50 cm³/rev (depending on specific configuration).
