Performance Features
-
High-Efficiency & Stable High-Pressure Operation: Equipped with innovative pressure control, pressure balance mechanisms, and an original 3-point ring support system, ensuring outstanding performance at high pressures up to 21 MPa (214 kgf/cm²), suitable for heavy-duty industrial scenarios.
-
Low Vibration & Noise: The 3-point support system for the control piston and bias piston enhances ring stability, minimizing vibration and enabling quiet operation—ideal for noise-sensitive working environments such as precision machining workshops.
-
High-Precision Response: An innovative ring stopper eliminates excessive ring displacement, ensuring high-precision operation during startup, shutdown, and load changes, effectively reducing hydraulic system errors.
-
Easy Maintenance: Pressure and discharge rate adjustment mechanisms are located on the same side of the pump, simplifying maintenance and reducing downtime, which helps improve production efficiency.
-
Energy-Saving & Durable: New mechanical innovations minimize power loss, especially at full cutoff, achieving high-efficiency operation and reducing energy consumption; the high-quality material and precision manufacturing extend the pump’s service life.
Application Scope
Nachi VDC-1A-2A2 (foot mounting) and VDC-1B-2A2 (flange mounting) are widely used in various heavy-duty industrial fields, including large-scale machine tools, high-pressure injection molding machines, hydraulic presses, engineering machinery, and other hydraulic systems that require stable fixed discharge rate and high-pressure operation. Their compact design and reliable performance make them ideal for systems with limited installation space and high load requirements.
Note
1. The pressure adjustment range is based on the standard configuration (Type 5); please refer to the official manual for other configurations. 2. The rotational speed should not exceed the maximum limit to avoid damage to the pump; over-speed operation may lead to reduced service life or equipment failure. 3. For matching motors and accessories, please consult Nachi’s official technical documentation or authorized distributors to ensure compatibility and safe operation. 4. Regular maintenance and inspection are recommended to ensure the pump’s stable performance and extend its service life..
