Vickers Type VQ Series Double Vane Pump | 4535VQ, 2520VQ, 3525VQ | P/N 433291

Vickers Type VQ Series High-Performance Double Vane Pumps

Product Overview: The VQ Series double vane pump is the definitive “Power Heart” for global construction machinery and heavy-duty industrial systems. Featuring patented Intra-Vane technology, the VQ series is specifically engineered for rigorous high-pressure and high-speed environments. This featured range highlights core frame sizes including 2520VQ, 3520VQ, 3525VQ, 4520VQ, and the high-flow 4535VQ. We specifically offer high-spec models such as 4535VQ60A38-1CC20 (P/N 433291) and 2520VQ-17A5-11C-20. Utilizing a precision pressure-balanced construction, this series delivers massive power while maintaining exceptional silent operation and extended cartridge life.

Key Technical Advantages:

• Dual-Circuit Independent Supply: The double pump configuration allows a single drive shaft to power two independent cartridges. The shaft-end (large pump) and cover-end (small pump) can supply primary and auxiliary circuits separately, simplifying plumbing and reducing costs.

• Patented Intra-Vane Design: Features a pressure-balancing mechanism within the vanes, drastically reducing wear against the cam ring. This ensures stable volumetric efficiency throughout thousands of hours of high-frequency operation.

• Rapid Maintenance with Cartridge Kits: The modular “drop-in” design allows performance to be restored in minutes by swapping the internal cartridge without disconnecting the pump housing, significantly reducing downtime.

• High Pressure & Dynamic Response: Optimized for mobile machinery, the VQ series supports continuous pressures up to 21 MPa. It provides a precise, smooth flow output even under violent engine speed fluctuations.

• Target Applications: Truck crane steering and hoisting systems, injection molding power units, aluminum extrusion presses, refuse compactors, and various mobile hydraulic equipment.
