VDC Series Variable Vane Pump | VDC-1A-F40A/B/C/D-20 | High Pressure

VDC Series (VDC-1A-F40) High-Performance Variable Displacement Vane Pumps

Product Overview: The VDC Series variable vane pumps are the definitive power core for hydraulic systems prioritizing “High-Pressure Stability” and “Energy Efficiency.” Featuring a unique pressure compensation mechanism, this series automatically adjusts output flow based on load demand. This range highlights the comprehensive 40cc displacement lineup: VDC-1A-F40A-20, VDC-1A-F40B-20, VDC-1A-F40C-20, and VDC-1A-F40D-20. Utilizing precision-machined internal profiles and a reinforced housing, the VDC series maintains low-noise operation even under high-pressure conditions while significantly reducing system heat generation by minimizing overflow loss—making it the ideal choice for modern precision machining.

Key Technical Advantages:

• Multi-Stage Pressure Ranges: Available in four adjustment segments: A (0.8-7 MPa), B (1.5-14 MPa), C (2-17.5 MPa), and D (3-21 MPa), catering to everything from low-pressure circulation to high-pressure clamping.

• Superior Energy Savings: Sensitive pressure compensation control ensures that once the set pressure is reached, displacement automatically drops to near zero, drastically cutting power consumption and oil heating.

• Peak Silent Performance: Optimized 12-vane design and high-precision silencing grooves drastically reduce pressure pulsation and structural vibration, meeting modern industrial silent standards.

• High Response & Stability: The variable mechanism reacts instantaneously to load changes, providing smooth transitions during actuator reversals to ensure high machining repeatability.

• Target Applications: CNC machine tool hydraulics, specialized machinery, plastic machinery, hydraulic lifting platforms, and high-pressure industrial power units.
