Vickers Type 2520V 2520VQ Double Vane Pump | 2520V21A14, 2520V17, 2520VQ21A12 | Intra-Vane

Vickers Type 2520V & 2520VQ Series Intra-Vane Double Hydraulic Pumps

Product Overview: The Vickers 2520V and 2520VQ Series are the performance benchmarks for double vane pumps in the hydraulic industry. As high-efficiency Intra-Vane power units, this series allows for the integration of two independent displacement cartridges on a single drive shaft, enabling high-low pressure dual-circuit control or combined high-flow delivery. This selection features core models: 2520V21A14-1CC22R, 2520V-14A5-1A22, 2520V17, and the enhanced 2520VQ-21-A-12-1-CC-20-R. Utilizing a unique intra-vane structure, the 2520V/VQ series maintains exceptionally smooth operation and extended component life even at continuous pressures up to 17.2 MPa (2500 PSI).

Key Technical Advantages:

• Patented Intra-Vane Technology: By reducing the vane-tip loading against the stator, friction and wear are significantly minimized, ensuring maximum volumetric efficiency even under high-pressure and high-speed cycles.

• Independent Dual Output: The 2520 frame size supports diverse displacement combinations (e.g., 21GPM + 14GPM), allowing for automatic high-low pressure synergy that optimizes energy efficiency and reduces system heat generation.

• VQ Mobile-Duty Enhancement: The 2520VQ series is engineered specifically for harsh construction environments, offering superior shock resistance and speed capabilities up to 2700 RPM.

• Modular “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, drastically cutting downtime.

• Target Applications: Injection molding machines, die-casting equipment, brick presses, wheel loaders, refuse trucks, and diverse industrial Hydraulic Power Units (HPU).
