Product Description
Nachi PVK-2B-505 Series Main Hydraulic Pump for ZX48 Excavator
Product Overview: The Nachi PVK-2B-505 series is a high-performance double axial piston variable pump specifically engineered for 4 to 5-ton hydraulic excavators, such as the Hitachi ZX48 and ZX50. Renowned for its exceptional power density and compact architecture, the PVK series maximizes space efficiency in tight engine compartments. Utilizing sophisticated dual-pump integration, it automatically modulates displacement based on load pressure, ensuring smooth, powerful compound movements for travel, swing, and boom operations.
Key Technical Advantages:
Precise Variable Modulation: Equipped with advanced Load Sensing regulators. Models like PVK-2B-505-CN-4962E and 4962F achieve precise on-demand flow delivery, effectively preventing engine stalls and optimizing fuel economy.
Heavy-Duty Durability: Built for grueling construction environments. The high-strength housing supports extended, high-frequency digging cycles under rated pressure, offering superior resistance to shock loads.
