Product Description
Nachi PVD Series Hydraulic Main Pumps for Mini Excavators
Product Overview: The Nachi PVD series is the premier power benchmark for mini excavator hydraulic systems worldwide. Engineered specifically for the 3-ton to 6-ton excavator class (compatible with brands like Kubota, Yanmar, Komatsu, and Takeuchi), these high-pressure pumps are renowned for their “Piston + Gear Pump” triple-integrated design. Featured models like the PVD-2B-38L3-17G-2230A and PVD-2B-40P-6G3-4515H deliver two independent variable flows and one constant gear pump flow within a single compact unit. This ensures balanced power distribution during complex simultaneous functions—such as traveling, swinging, and boom lifting—providing smooth handling and superior fuel economy.
Key Technical Advantages:
Efficient Triple-Integrated Architecture: Combines two variable piston pumps and one fixed gear pump on a single drive shaft, maximizing engine compartment space and simplifying pilot hydraulic plumbing.
Precision Power Allocation: Utilizes advanced constant power control logic to modulate displacement in real-time based on load, preventing engine stalling and optimizing fuel efficiency.
Superior Suction & High-Pressure Durability: Rated for continuous operation at 21-25 MPa (3000-3600 PSI). The reinforced swashplate structure ensures long-term service life in harsh construction environments.
Smooth Operational Feedback: Optimized valve plate designs effectively suppress pressure ripples, resulting in highly responsive joysticks and synchronized multi-function performance.
100% OEM Standard Compatibility: Manufactured to strict Nachi factory specifications, ensuring splined shafts, mounting flanges, and regulator porting align perfectly for a seamless “drop-in” replacement.
