Vickers Type VQ VQH Series Vane Pump | 20VQ, 25VQ, 35VQ, 45VQ | 35VQ38, 35VQ45

Vickers Type VQ & VQH Series High-Pressure Mobile Vane Pumps

Product Overview: The VQ Series and Enhanced VQH Series are the premier power solutions engineered for the grueling demands of mobile and construction machinery. As the global benchmark for fixed displacement vane pumps, the VQ series features Vickers’ patented Intra-vane technology. This range features core models: 35VQ38, 35VQ45A-1A20L, 35VQ-30A-1C-20, and covers all frame sizes: 20VQ, 25VQ, 35VQ, and 45VQ. Renowned for high shock resistance and operating pressures up to 21.0 MPa (3000 PSI), this series is the definitive choice for loaders, cranes, and material handling equipment.

Key Technical Advantages:

• Patented Intra-vane Technology: This dual-vane structure automatically balances radial hydraulic loads, significantly reducing vane-tip friction against the stator—ensuring superior durability under 3000 PSI continuous operation.

• High-Speed & Dynamic Response: Specifically matched for mobile engine speeds up to 2700 RPM, maintaining full power output despite temperature fluctuations or rapid cycle operations.

• VQH Reinforced Series: Models like 35VQH38 utilize hardened materials and precision seals, optimized for higher pressure peaks and specialized hydraulic fluids.

• Modular “Drop-in” Cartridge Maintenance: The internal pump core is a modular unit. Maintenance is streamlined—swap the internal cartridge on-site to restore OEM-level performance without disconnecting heavy plumbing, drastically cutting downtime.

• Target Applications: Excavators, wheel loaders, refuse trucks, material handlers, compactors, and mobile construction hydraulic systems.
