Product Description

VDN Series (1B) High-Performance Variable Vane Uni-Pumps

Product Overview: The VDN Series variable volume Uni-Pumps represent a cutting-edge solution for “High Integration” and “Low Noise” in hydraulic systems. Featuring the advanced Uni-Pump (Motor-Pump Integration) design, these units use direct-coupling technology to drastically reduce installation space while eliminating vibrations caused by coupling misalignment. This range highlights core specifications including VDN-1B-1A2-J-6311C, VDN-1B-1A4-J-6311C, and VDN-1B-0A3-J-6311C. Utilizing a precision pressure compensation mechanism, the VDN series automatically de-strokes to minimum displacement during pressure-holding phases, delivering significant energy savings and maintaining exceptionally low oil temperatures.

Key Technical Advantages:

  • Highly Integrated Uni-Pump Design: Compact layout integrates the motor and pump head, eliminating the need for extra pump brackets and couplings, resulting in lower noise and a smaller footprint.

  • Intelligent Pressure Compensation: Equipped with a high-sensitivity regulator. Once the system hits the set pressure, flow drops near zero, eliminating overflow heat and saving over 30% energy compared to fixed systems.

  • Ultimate Silent Performance: Finely balanced rotor assemblies and the integrated structure ensure exceptionally low decibel levels during both full-load operation and pressure-holding stages.

  • Rapid Dynamic Response: The sensitive variable mechanism reacts instantaneously to actuator reversals, ensuring the machining precision and stability of CNC equipment.

  • Target Applications: CNC machine chuck clamping systems, automated feeding mechanisms, precision grinding machines, tapping units, and compact hydraulic power units.
