Vickers Type 4520VQ 4535VQ Double Vane Pump | 4520VQ60A8, 4535VQ60A38

Vickers Type 4520VQ & 4535VQ High-Pressure Double Vane Pumps

Product Overview: The 4520VQ and 4535VQ Series are the definitive power sources for heavy-duty mobile hydraulic systems. As double fixed displacement pumps, this series integrates two independently operating intra-vane cartridges onto a single drive shaft, designed to provide high-low flow splitting or independent dual-circuit supply for complex systems. Featured here are the high-flow powerhouse models: 4520VQ60A8, 4535VQ, and 4535VQ60A38. Powered by Vickers’ patented Intra-vane technology, the 4520VQ/4535VQ series maintains exceptional shock resistance and low operational noise even under continuous pressures up to 21 MPa (3000 PSI).

Key Technical Advantages:

• High-Flow Dual Output: The 45 series shaft end delivers a massive 60 GPM output, perfectly suited for the rapid movement requirements of large hydraulic actuators.

• Patented Intra-vane Technology: The unique vane-within-a-vane structure balances tip loads, significantly extending the service life of both stators and vanes while maximizing volumetric efficiency.

• Rapid Cartridge Maintenance: Both the primary and secondary cartridges feature a “drop-in” design. Maintenance is streamlined—swap the internal core on-site to restore factory performance without disturbing heavy housings or main plumbing.

• Superior Power-to-Weight Ratio: The robust cast iron housing provides massive power density, saving valuable installation space in heavy-duty vehicles.

• Target Applications: Heavy loaders, graders, excavator auxiliary systems, scrap metal balers, and large-scale road construction machinery.
