Vickers Type 45VQ Series Vane Pump | 45VQ42A, 45VQ60A | High Pressure

Vickers Type 45VQ Series High-Pressure & High-Flow Vane Pumps

Product Overview: The 45VQ Series vane pump is the definitive performance standard for global heavy-duty mobile hydraulic power. As the largest displacement single pump in the VQ family, it is specifically engineered to withstand extreme pressures up to 21 MPa (3000 PSI) and severe load shocks. Featured here are the powerhouse models 45VQ42A-1A20 and 45VQ60A-1AL-22R. Powered by Vickers’ patented Intra-vane technology, the 45VQ series delivers massive flow output while significantly reducing stator wear and maximizing volumetric efficiency. Its signature Cartridge Design enables “minute-level” on-site repairs, ensuring maximum uptime for your heavy machinery.

Key Technical Advantages:

• Extreme Operating Pressure: Rated operating pressures reach a steady 21 MPa (3000 PSI), offering industry-leading shock resistance for high-intensity excavator and loader duty cycles.

• Patented Intra-vane Technology: The unique vane-within-a-vane structure balances tip loading against the stator, maintaining exceptional durability and low decibel levels even at high speeds.

• Modular Cartridge Kits: Features a “drop-in” cartridge design. Maintenance is streamlined—swap the internal core to restore factory-level performance without disturbing expensive housings or plumbing.

• High Efficiency & Energy Saving: Optimized pressure-balanced side plates ensure minimal internal leakage across the entire pressure spectrum, boosting total system energy conversion.

• Target Applications: Large hydraulic excavators, mining loaders, scrap metal shears, road-building equipment, and heavy-duty industrial Hydraulic Power Units (HPU).
