Product Description
Nachi PVD Series Hydraulic Pilot Charge Gear Pump for Excavators
Product Overview: The Nachi PVD series pilot gear pump is a critical auxiliary power component for mini excavator hydraulic systems. Typically mounted as the rear pump of the main piston unit, it is responsible for providing stable pilot control pressure and system charge flow. Covering a comprehensive range from the compact PVD-0B-18 to the high-flow PVD-3B-60, this series utilizes precision-ground gear sets and high-strength alloy housings. It ensures that the excavator’s pilot controls (joysticks) remain highly responsive and the hydraulic circuit operates with consistent efficiency.
Key Technical Advantages:
Superior Pilot Control Stability: Optimized gear-meshing technology significantly reduces pressure pulsations, maintaining constant pilot pressure and eliminating operational lag.
High Volumetric Efficiency & Self-Priming: Specifically designed to support PVD-1B/2B/3B main pumps, providing continuous charge flow to prevent cavitation under high-load conditions.
Heavy-Duty Wear-Resistant Build: Engineered with specialized hardened journals and thrust plates to withstand frequent start-stop cycles and fluctuating oil temperatures.
100% OEM-Standard Compatibility: Manufactured to strict Nachi factory specifications (e.g., PVD-0B-24P, PVD-2B-4), ensuring that mounting flanges and spline shafts align perfectly with original equipment.
Compact & Reliable Performance: The modular design allows for seamless integration behind the main pump, delivering exceptional durability in harsh off-road environments.
Detailed Models & Parameters:
Core Series: Nachi PVD Series (Gear/Pilot Section).
Representative Models: PVD-0B-18, PVD-0B-24P, PVD-1B, PVD-2B-2, PVD-2B-4, PVD-3B-54, PVD-3B-60.
Target Equipment: 1.0T, 1.5T, 2.0T, 3.5T, 5.0T, 6.0T Mini and Small Excavators.
