Vickers Type 25VQ Vane Pump | 25VQ14A, 25VQ17A-1C20, 25VQ17A-1C22R | Intra-Vane

Vickers Type 25VQ Series High-Performance Intra-Vane Pumps

**Product Overview: ** The Vickers 25VQ Series fixed displacement vane pump is a globally recognized benchmark for heavy-duty power in the hydraulic industry. Engineered as a high-speed Intra-Vane power unit specifically for high-pressure, high-speed, and demanding duty cycles, the 25VQ series is the definitive choice for mobile equipment and high-performance industrial power units. This selection features core models: 25VQ14A-1C20, 25VQ17A-1C20, and 25VQ17A-1C22R. Utilizing its unique intra-vane structure, the 25VQ series maintains exceptional volumetric efficiency and superior durability even at continuous pressures up to 21.0 MPa (210 Bar).

Key Technical Advantages:

• Patented Intra-Vane Technology: By reducing the vane-tip loading against the stator, friction and wear are significantly minimized. This ensures high mechanical efficiency and a service life of thousands of hours, even under fluctuating fluid viscosity or high-pressure cycles.

• High-Speed Capability: Optimized for mobile machinery, the 25VQ supports speeds up to 2700 RPM, far exceeding standard industrial pumps, making it ideal for diesel engine-driven systems.

• 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 from the machine.

• Low Noise & Vibration Resistance: The engineered stator curve and multi-vane rotor effectively suppress flow pulsations and system vibrations, ensuring smooth and quiet operation even under peak loads.

• Target Applications: Wheel loaders, excavators, refuse trucks, material handling equipment, injection molding machines, and various mobile Power Units.
