Description
Nachi Vane Pump VDC-3A-1A5 & VDC-3B-1A5 Specifications
Nachi VDC-3A-1A5 and VDC-3B-1A5 are super ultra-high pressure variable displacement vane pumps designed for industrial hydraulic systems, featuring stable performance, low noise, and high efficiency. This document provides detailed technical parameters, model interpretation, and key features to help users quickly understand and select the product. Suitable for machinery, automation, engineering equipment, and other fields requiring reliable hydraulic power with super ultra-high pressure demand.
Model Interpretation
The model codes of Nachi VDC series vane pumps have clear meanings, helping to identify product specifications quickly:
-
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.
Application Scope
Nachi VDC-3A-1A5 and VDC-3B-1A5 vane pumps are widely used in various industrial fields requiring super ultra-high pressure hydraulic power, including heavy-duty hydraulic presses, large-scale injection molding machines, heavy engineering construction machinery, high-precision automated production lines, ultra-high pressure precision hydraulic systems and high-pressure testing equipment. With stable displacement, super ultra-high pressure adjustment range and peak pressure, they are an ideal choice for medium and super ultra-high pressure hydraulic systems with strict requirements on pressure stability, durability, efficiency and pressure resistance.
Note
1. The parameters are standard values; actual performance may vary slightly according to the working environment and medium used.
2. It is recommended to use hydraulic oil that meets Nachi’s super ultra-high pressure specifications to ensure the service life and performance of the pump, avoiding damage caused by inappropriate oil quality, viscosity or impurity content.
3. For more detailed installation and maintenance guidelines, please refer to the official Nachi VDC series product manual.
