Vickers Type VQ Series Vane Pump | 45VQ, 35VQ, 25VQ, 20VQ | 45VQ-60A, 20VQ8A

Vickers Type VQ Series High-Performance High-Pressure Vane Pumps

Product Overview: The VQ Series is globally recognized as the benchmark for “High Pressure and Reliability” in the hydraulic industry. These fixed displacement vane pumps are specifically engineered for high-speed, heavy-duty applications in both industrial and mobile machinery (e.g., construction vehicles). This featured range highlights core specifications including 20VQ, 25VQ, 35VQ, and high-flow models 45VQ-42A, 45VQ-45A, 45VQ-50, 45VQ-57, and 45VQ-60A. Utilizing the patented Intra-Vane technology, the VQ series maintains exceptional volumetric efficiency even at pressures up to 21 MPa—serving as the definitive power choice for injection molding and heavy construction equipment worldwide.

Key Technical Advantages:

• Patented Intra-Vane Technology: The unique double-vane design automatically compensates for vane-tip wear, ensuring factory-level efficiency for thousands of hours while minimizing stress on the cam ring.

• High Speed & Pressure Capability: Optimized for engine-driven environments, the VQ series supports frequent pressure pulsations and high-speed operation, perfectly matching the power demands of excavators and cranes.

• Ultimate Silent & Low Pulsation: The 10/12-vane rotor system and precision-ground technology provide highly smooth flow output, significantly reducing hydraulic vibration and environmental noise.

• Modular Cartridge Kit Design: Features a “drop-in” cartridge system. During maintenance, simply replace the internal kit to restore 100% performance without disconnecting plumbing, drastically reducing downtime and costs.

• Target Applications: Plastic injection molding machines, die-casting machines, truck cranes, wheel loaders, scrap metal shears, and heavy-duty industrial power stations.
