Product Description
Nachi PVD Series Hydraulic Main Pump for 1.5-2 Ton Mini Excavators
Product Overview: The Nachi PVD series is the premier power core for hydraulic systems in 1.5-ton to 2.0-ton mini excavators worldwide. This series features a highly integrated combination of variable displacement piston pumps and fixed displacement gear pumps. Featured models like the PVD-0B-18P, PVD-1B-32CP, and PVD-2B-44P are specifically engineered for compound movements in confined spaces, delivering precise pressure to travel, swing, and implement circuits simultaneously. Its superior variable control logic ensures a seamless transition between heavy digging and grading operations.
Key Technical Advantages:
Highly Integrated Multi-Pump Design: Integrates dual variable piston pumps with single/dual gear pumps in a single housing, significantly saving installation space for compact excavator compartments.
Precision Power Matching: * PVD-1B-24P / 32CP: Features excellent constant power control, automatically modulating displacement based on load to prevent engine stalling and maximize fuel efficiency.
Durable Rotating Groups: Engineered with specialized hardened pistons and valve plates designed to withstand hydraulic breaker shocks and all-weather duty cycles, effectively extending service intervals.
Superior Operational Smoothness: Optimized displacement regulation ensures stable flow distribution during multi-function operations (e.g., traveling while lifting the boom) without lag.
100% OEM-Standard Compatibility:
Specific configuration codes (e.g., 4743G, 5288A) are deeply calibrated to ensure pressure cut-off points and flow slopes perfectly match the original equipment specifications.
