Product Description
3520VQ Series High-Performance High-Pressure Double Vane Pumps
Product Overview: The 3520VQ Series is recognized as the “Power Backbone” for mobile hydraulic systems. Engineered for harsh operating environments, this high-pressure double vane pump provides two independent flow outputs from a single drive shaft—perfectly matching synchronized steering and work circuits. This range features precision models including 3520VQ-35A5-1CC, 3520VQ35A11-1BB20, and the specially sealed 3520VQS25AM11S. Utilizing core Intra-Vane technology, the 3520VQ series maintains exceptional service life and ultra-low operational noise even at peak pressures up to 21 MPa.
Key Technical Advantages:
Independent Dual-Output Structure: Combining 35VQ and 20VQ cartridges, this series allows for two different displacement outputs on one shaft, drastically saving installation space and reducing system complexity.
Heavy-Duty Intra-Vane Design: Features internal pressure-balanced vanes that significantly reduce friction against the cam ring, ensuring high reliability under frequent shock loads common in construction machinery.
Modular Cartridge Kit Design: The entire 3520VQ series utilizes a “drop-in” cartridge system. On-site maintenance is simplified—replace internal components without disconnecting pump plumbing, minimizing equipment downtime.
Superior High-Temperature Performance: Precision-ground flexible side plates ensure that the pump maintains volumetric efficiency above 90% even in extreme environmental temperatures.
Target Applications: Wheel loaders, scrapers, excavator steering pumps, forklift hydraulics, and mining rig power sources.
