DVQ20 Series High-Performance Variable Displacement Vane Pumps

Product Overview: The DVQ20 Series variable displacement vane pumps are the premier choice for achieving “High Precision Pressure Control” and “Significant Energy Savings” in industrial hydraulic stations. Featuring a high-sensitivity pressure compensation mechanism, these pumps automatically adjust output displacement based on load demand. Once the preset pressure is reached, the pump de-strokes to a minimum flow state. This range highlights core specifications including DVQ20-17-F-RAB-02, DVQ20-28-F-RAB, and DVQ20-14-F-RAB-02. Utilizing unique silencing grooves and side-plate pressure compensation technology, the DVQ20 series maintains exceptionally low noise and minimal oil temperature rise during prolonged pressure-holding phases.

Key Technical Advantages:

• Automatic Pressure Compensation: The variable design ensures the pump only delivers the required flow. During pressure-holding, the pump automatically reduces eccentricity, eliminating overflow heat and saving 30% – 50% energy compared to fixed systems.

• Ultimate Silent Performance: Precision-ground vanes and cam ring profiles combined with optimized suction port geometry ensure minimal mechanical noise across all pressure ranges.

• Rapid Dynamic Response: The sensitive variable mechanism reacts instantaneously to actuator movements (e.g., hydraulic cylinders or clamps), ensuring consistent processing stability for CNC equipment.

• Compact & Easy Integration: Standard F (Flange Mounting) design provides a space-saving footprint, ideal for integration within tight CNC machine hydraulic tank enclosures.

• Target Applications: CNC lathe clamping systems, precision grinding machines, automated production lines, shoe-making machinery, and energy-saving hydraulic power units.
