Product Description
VDC Series (1B/2B) High-Performance Small Variable Vane Pumps
Product Overview: The VDC Series variable volume vane pumps are the definitive solution for hydraulic power units seeking “Miniaturization, Silent Operation, and High Efficiency.” Featuring a precision pressure compensation mechanism, these pumps automatically adjust output flow based on system load demand. This range features core models including VDC-1B-2A3-20, VDC-2B-1A3-20, VDC-2B-2A3-20, and the specialized pressure-setting model VDC-2B-1A5-E35. Utilizing unique silencing grooves and side-plate compensation technology, the VDC series maintains exceptionally low temperature rise during prolonged pressure-holding—making it the standard choice for precision machine tools and light industrial automation.
Key Technical Advantages:
Superior Energy Efficiency: The variable displacement design ensures that once the system reaches its set pressure, flow automatically drops to a minimum, drastically cutting power consumption.
Ultimate Silent Operation: High-precision ground vane assemblies and an optimized housing structure ensure extremely low decibel levels even under full load.
Rapid Dynamic Response: The sensitive variable mechanism reacts instantaneously to actuator reversals (e.g., hydraulic cylinders), ensuring consistent machining precision.
Compact & Easy Installation: The miniaturized design is ideal for integration within tight hydraulic station enclosures, with standardized mounting holes for easy replacement.
Target Applications: CNC lathe clamping systems, precision grinding machines, shoe-making machinery, woodworking machines, automated locking mechanisms, and compact hydraulic power units.
