Vickers Type 2520VQ Series Double Vane Pump | 2520VQ21, 2520VQ12

Vickers Type 2520VQ Series High-Performance Double Vane Pumps

Product Overview: The 2520VQ Series stands as the global power standard for heavy-duty hydraulic systems. As a high-pressure double fixed displacement vane pump, it combines 25VQ and 20VQ modules, enabling a single drive shaft to power two independent hydraulic circuits reliably. This range features core specifications including the 2520VQ21 series and the fully configured model 2520VQ21C12-11CA20. Utilizing patented Intra-Vane technology, the 2520VQ series maintains exceptional volumetric efficiency even at pressures up to 21 MPa—serving as the definitive power choice for injection molding and mobile machinery like cranes.

Key Technical Advantages:

• Dual-Circuit Independent Supply: The 2520VQ integrates two independent cartridges within one housing. The large pump (shaft end) provides main system power, while the small pump (cover end) supplies auxiliary flow, significantly optimizing system footprint.

• Patented Intra-Vane Technology: The unique double-vane design automatically compensates for vane-tip wear, drastically reducing contact stress against the cam ring and ensuring long-term durability under heavy shock loads.

• Modular Cartridge Kit Maintenance: Features a replaceable “drop-in” cartridge system. During maintenance, performance can be restored in minutes by simply swapping the internal kit without disconnecting complex plumbing, drastically reducing downtime.

• Ultimate Silent & Low Pulsation: Precision-ground 10/12-vane rotor systems provide highly smooth flow output, effectively lowering system vibration and improving the operational environment.

• Target Applications: Truck cranes, injection molding machines, die-casting machines, scrap metal balers, and various heavy-duty industrial energy-saving power units.
