Nachi Vane Pump VDC-3A-1A5 & VDC-3B-1A5 Specifications
Model Interpretation
-
VDC: Series name, representing Nachi high-pressure variable displacement vane pump.
-
3: Pump size, indicating the basic structural size of the pump (larger than the VDC-2 series).
-
A/B: Mounting method (A: Foot type mounting; B: Flange mounting optional).
-
1: Ring size, corresponding to the matching size of the pump ring.
-
A: Flow characteristics, meaning constant discharge type for stable flow output.
-
5: Pressure adjustment range, corresponding to the super ultra-high pressure regulation specification for the VDC-3 series (higher than the “4” suffix model, with wider pressure range and higher peak pressure, designed for more demanding high-pressure working conditions).

Key Features
-
Super Ultra-High Pressure Performance: Withstand peak pressure up to 3500 psi (246.1 kgf/cm²), and adjustable pressure range of 290-2100 psi, suitable for super ultra-high pressure hydraulic systems requiring stable, continuous and high-pressure output.
-
Stable Operation: Adopts 3-point ring support system and further upgraded pressure control mechanism, ensuring stable discharge rate even in super ultra-high pressure range, effectively reducing pressure fluctuations and ensuring long-term system stability.
-
Low Vibration & Noise: Advanced structural optimization, precision machining and noise reduction design minimize vibration and noise, providing a quiet operation environment, suitable for precision machinery, indoor equipment and high-demand super ultra-high pressure working scenarios.
-
Easy Maintenance: Pressure and discharge rate adjusting mechanisms are located on the same side, simplifying maintenance and handling, reducing equipment downtime and improving overall work efficiency.
-
High Efficiency & Durability: Innovative mechanical design reduces power loss, improving overall system efficiency and energy saving; further enhanced high-strength reinforced cast iron material enhances wear resistance, pressure resistance and corrosion resistance, ensuring long service life under super ultra-high pressure working conditions.
