Vickers Type Double Vane Pump | 4535VQ, 4525VQ, 2520VQ, 3525VQ | Intra-Vane

Vickers Type V & VQ Series High-Performance Intra-Vane Double Pumps

Product Overview: The Vickers V and VQ Series Double Pumps are the definitive power source for heavy-duty hydraulic systems worldwide. Utilizing advanced Intra-Vane technology, this series integrates two independent displacement cartridges onto a single drive shaft, enabling exceptionally flexible power distribution. This selection features core high-performance models: 4535VQ, 4525VQ, 4520VQ, 3525VQ, and precision specifications 2520V12-A5-1AA-20-282 and 2520VQ-21-A-12-1-CC-20-R. With its unique intra-vane structure, this series maintains superior durability and low-noise performance even at pressures up to 21.0 MPa (3050 PSI), making it the ideal choice for injection molding and mobile machinery.

Key Technical Advantages:

• Patented Intra-Vane Efficiency: This design significantly reduces the vane-tip loading against the stator, minimizing friction and ensuring a long mechanical service life even under continuous high-pressure and high-speed cycles.

• Dual-Circuit Synergy (High-Low Control): The double pump architecture allows the system to adjust based on load: combining flows for rapid movement or isolating a single pump for pressure holding, significantly optimizing energy efficiency and reducing heat generation.

• Rapid “Drop-in” Cartridge Maintenance: Internal components are housed in self-contained cartridges. Maintenance is streamlined—swap the internal cores on-site in minutes without disconnecting heavy plumbing from the machine.

• Optimized for Industry & Mobile Use: The V Series is acoustically optimized for factory automation, while the VQ Series is ruggedized for the shock resistance and high-speed demands of construction machinery.

• Target Applications: Injection molding machines, die-casting equipment, CNC shears, material handling, refuse trucks, and heavy-duty industrial Hydraulic Power Units (HPU).
