High-Performance VQ Series Hydraulic Vane Pumps: Reliable Fluid Power Solutions

Core Design & Key Advantages

1. Fixed Displacement EfficiencyThe VQ series adopts a proven fixed displacement vane design, ensuring steady flow output at a given speed to support precise actuation of hydraulic cylinders and motors. This design minimizes internal leakage, optimizing energy utilization and reducing operational costs.
2. Quiet & Low-Vibration OperationAdvanced vane geometry and balanced rotor construction significantly reduce noise and vibration during operation. This feature enhances operator comfort and extends the service life of connected hydraulic components by lowering mechanical stress.
3. Heavy-Duty DurabilityBuilt with high-strength cast iron housings and wear-resistant vane materials, these pumps withstand harsh working environments—including exposure to high temperatures, pressure spikes, and hydraulic fluid contaminants. The robust build ensures minimal maintenance and a long service lifespan, even in continuous-duty applications.
4. Easy Installation & VersatilityThe VQ series pumps feature standardized mounting interfaces and port configurations, enabling seamless integration into new hydraulic systems or direct replacement of outdated units. Their compact footprint saves valuable installation space without sacrificing power output.
