Key Features of Nachi Double Vane Pump VDC-13A(B)-2A3-1A*20

  • High-Pressure Stability: Equipped with innovative pressure control, pressure balance mechanisms, and an original 3-point ring support system, the VDC-13A(B)-2A3-1A*20 achieves outstanding performance at high pressures up to 2000 psi (140 bar), ensuring stable operation even in harsh high-pressure working conditions.
  • Low Vibration & Noise: The adoption of a 3-point support system for the control piston and bias piston effectively reduces ring vibration, delivering quiet operation and a comfortable working environment, which is crucial for precision equipment and indoor applications.
  • High Precision & Quick Response: An innovative ring stopper eliminates excessive ring displacement, enhancing the pump’s response speed and ensuring high-precision operation at all times—whether during startup, shutdown, or load changes.
  • Energy-Saving & High Efficiency: New mechanical improvements minimize power loss, especially during full cutoff, optimizing energy utilization and reducing operational costs. Compared with traditional hydraulic pumps, it achieves better energy-saving effects in pressure-holding scenarios.
  • Easy Maintenance: The pressure adjustment and discharge rate adjustment mechanisms are located on the same side of the pump, simplifying maintenance and handling, reducing downtime, and improving work efficiency.
  • Compact & Space-Saving Design: As a double vane pump, it integrates two pump units into one body, sharing a single motor and shaft, which saves installation space and facilitates integration into compact hydraulic systems.
