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.

  • OEM-Grade Compatibility: This series is the standard OEM pump for Hitachi ZX48 and similar models. Strict adherence to OEM manufacturing standards ensures a perfect “plug-and-play” fit for mounting flanges, spline shafts, and porting.

  • Quiet Operation: Optimized valve plate designs significantly dampen operating noise, enhancing operator comfort while complying with strict environmental decibel regulations.
