Vickers Type VQ Series Double Vane Pump | 3525VQ, 4535VQ, 4520VQ | High Pressure

Vickers Type VQ Series High-Performance Double Vane Pumps

Product Overview: The VQ Series Double Vane Pump is the global durability benchmark for mobile and heavy industrial hydraulic systems. Engineered with specialized Intra-vane technology for high-pressure and high-speed operation, this series integrates two heavy-duty cartridge kits within a single housing to deliver multi-circuit output and exceptional power density. This range features premium specifications: 3520VQ, 3525VQ, 4520VQ, 4525VQ, and the high-flow 4535VQ, including the specific configuration 3525VQ3817-11CC-20L. Its unique modular design not only minimizes operational noise but also provides unparalleled convenience for field maintenance.

Key Technical Advantages:

• Superior Pressure Durability: Utilizing Intra-vane technology, rated pressures reach 21 MPa (3000 PSI), effortlessly handling frequent pressure transients and load shocks in construction machinery.

• Dual-Output Efficiency: Integrated dual-cartridge design allows flexible configuration of Shaft-end (Large) and Cover-end (Small) flows, catering to multi-circuit split or merged flow requirements.

• Modular Cartridge Kits: Features “drop-in” cartridge design. Maintenance is streamlined—swap the cartridge kit without disconnecting main plumbing to restore factory performance and minimize downtime.

• Ultimate Silence & Volumetric Efficiency: Precision-ground stator geometry and 10-vane rotors ensure smooth fluid output and drastically reduced operational noise even under full load.

• Target Applications: Wheel loaders, excavators, scrapers, scrap metal shears, mining machinery, and heavy industrial Hydraulic Power Units (HPU).
