Product Description
Nachi PVK-2B-505 Series Hydraulic Main Pumps for Mini Excavators
Product Overview: The Nachi PVK-2B-505 Series is the premier power source for mini excavator hydraulic systems worldwide. Designed as a high-efficiency tandem axial piston variable displacement pump, it is specifically engineered for 3-5 ton class machinery. Featured models like the PVK-2B-505-N-4962 and PVK-2B-505-CN-4962E integrate dual-pump outputs with an auxiliary gear pump system, delivering stable power for complex compound movements within an extremely compact footprint. The PVK series is the leading OEM choice for brands like Kubota, Komatsu, and IHI, renowned for its superior volumetric efficiency and robust contamination resistance.
Key Technical Advantages:
Highly Integrated Architecture: The tandem pump design minimizes housing size while ensuring independent oil supply for two circuits, perfectly supporting simultaneous travel and digging functions.
Precision Power Matching: Features sensitive pressure compensation control that modulates displacement in real-time based on load, preventing engine stalls and maximizing fuel efficiency.
Exceptional Durability: Constructed with high-strength materials and precision-ground piston groups to ensure an extended service life under the dusty, high-load conditions of modern construction sites.
Quiet Operational Profile: Optimized internal flow path designs significantly reduce noise levels during high-pressure cycles, meeting modern urban environmental standards.
100% Seamless Replacement: Strictly adheres to OEM mounting standards, ensuring “drop-in” compatibility for specific configurations like 4962 and 4554C on major excavator models.
