Product Description
Daikin Type VDS / VDR / VDC Series High-Performance Variable Vane Pumps
Product Overview: The VDS, VDR, and VDC Series are the premier choices for hydraulic systems prioritizing high-precision control and maximum energy efficiency. As variable displacement pumps featuring built-in Pressure Compensated control, they instantaneously adjust output flow based on real-time system pressure demands. This range features premium specifications including the single pump VDR-11A, the upgraded VDR-11B, and the double pump configuration VDR-11B-1A2-1A2-U-13. Utilizing a unique pressure-balanced construction, the pump automatically minimizes displacement once the preset pressure is reached, significantly lowering electrical costs and inhibiting system heat—making it the ideal green power core for modern machine tools.
Key Technical Advantages:
Superior Energy Saving: Equipped with high-sensitivity pressure compensation control. When system pressure reaches the preset limit (e.g., 7.0 MPa), the pump automatically transitions to a standby state, eliminating overflow loss and drastically reducing electricity costs.
Rapid Response & Stability: Specifically optimized for automated production cycles, providing ultra-short displacement switching times to ensure smooth actuator movement and precise positioning.
Low Noise Operation: Advanced stator geometry and precision-ground port plates ensure exceptionally low decibel levels even when operating in a high-pressure holding state, enhancing the workshop environment.
Highly Integrated & Compact: The VDS/VDR series supports multi-stage combinations (e.g., double pumps), saving installation space while offering flexible flow circuit configurations.
Target Applications: CNC machine tools, grinding machines, specialized machining centers, plastic molding equipment, footwear machinery, and various industrial Hydraulic Power Units (HPU).
