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

Product Overview: The VQ Series fixed displacement vane pumps are the global power standard for heavy-duty hydraulic systems. Specifically engineered to handle the high speeds, shock loads, and continuous high-pressure conditions of mobile machinery (e.g., construction vehicles), this range highlights core models including VQ15-31-LRAA, VQ25-47-L-RAA-01, VQ35-94-F-RAL-01, and the high-flow VQ45-216-F-RAB-02. Utilizing the patented Intra-Vane technology, the VQ series maintains exceptional volumetric efficiency even at pressures up to 21 MPa, effectively reducing heat generation and extending equipment service life.

Key Technical Advantages:

• Patented Intra-Vane Technology: The unique double-vane design automatically compensates for wear, drastically reducing contact stress against the cam ring and ensuring factory-level efficiency through thousands of hours of high-frequency pulsations.

• Superior Shock & High-Speed Performance: Optimized for engine-driven environments, the VQ series supports instantaneous pressure spikes and high operational speeds, making it the perfect choice for crane and loader hydraulic circuits.

• Ultimate Silent & Low Pulsation: The 10/12-vane rotor systems and precision-ground technology provide highly smooth flow output, significantly improving the noise environment of operator cabins and workshops.

• Modular Cartridge Kit Maintenance: Features a “drop-in” cartridge system. During maintenance, there is no need to dismantle the pump housing or plumbing; simply replace the internal kit in minutes to restore 100% performance, minimizing downtime.

• Target Applications: Truck cranes, wheel loaders, injection molding machines, die-casting machines, scrap metal balers, and heavy-duty industrial power units.
