Vickers Type 2520VQ 2520V Double Vane Pump | 2520VQ-17A5, 2520V14A8 | High Pressure

Vickers Type 2520V & 2520VQ Series High-Pressure Double Vane Pumps

Product Overview: The 2520V and 2520VQ Series represent the global benchmark for high-performance double hydraulic pumps. Featuring the classic Intra-Vane design, these series are engineered for high-pressure industrial and mobile applications requiring dual-circuit independent flow. This featured range includes core configurations: 2520VQ-17A5-11C-20, 2520VQ17A11-11CC-20, and 2520V14A8-1CC22R. Utilizing a unique vane-within-a-vane structure, these pumps maintain exceptionally low radial loads and operating noise even at peak pressures, making them the definitive power source for injection molding servo systems and construction machinery.

Key Technical Advantages:

• Intra-Vane Technology: Reduces the vane tip loading against the cam ring, significantly minimizing wear and ensuring extended service life even at the rated 21 MPa pressure.

• Efficient Double-Flow Output: A single shaft drives two independent cartridges (e.g., 17GPM + 11GPM), allowing for high-low pressure combinations or synchronized multi-circuit operations.

• Replaceable Cartridge Design: Maintenance is simplified—the pump does not need to be removed from the machine; only the internal cartridge kit requires replacement, drastically reducing downtime.

• Low Noise & High Volumetric Efficiency: The optimized 12-vane design provides excellent flow stability, typically maintaining a volumetric efficiency above 90%.

• Target Applications: Plastic injection molding machines, die-casting machines, mobile crane hydraulics, refuse trucks, and heavy-duty industrial power stations.
