Vickers Type VQ Series Intra-Vane Pumps for Injection Molding Machines

Product Overview: The Vickers VQ Series is the definitive power source for global injection molding machinery and mobile hydraulic systems. As the flagship of Intra-Vane technology, the VQ series is specifically engineered to handle high-frequency cycling, continuous high pressure, and high-speed operations. This selection features core models optimized for large-scale injection machines: single pumps 45VQ50A-1A30R, 45VQ60A-1A30R, and high-performance double pumps 2520VQ21A5-1AB20R, 4525VQ60A21-1AB20R. Utilizing a unique intra-vane design, the VQ series maintains superior volumetric efficiency and extended service life even at pressures up to 21.0 MPa (3050 PSI).

Key Technical Advantages:

• Optimized for Injection Machines: Designed for the rigorous mold opening/closing and pressure-holding cycles of injection molding, providing rapid response and minimizing system heat generation.

• Patented Intra-Vane Technology: Reduces radial loading of vanes against the stator, ensuring high mechanical efficiency and minimal wear even under low-viscosity fluid conditions or high-pressure cycles.

• Double Pump Versatility: Models like the 4525VQ support flexible combinations (e.g., 60GPM + 21GPM), enabling high-flow rapid filling and precise low-flow pressure holding.

• Rapid “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: Plastic injection machines, rubber presses, die-casting equipment, wheel loaders, refuse trucks, and heavy-duty industrial Power Units.
