Vickers VQH Series High-Pressure Mobile Vane Pump Cartridge Kits

Product Overview: The VQH Series Cartridge Kits are the definitive power restoration solution for heavy-duty mobile machinery operating under extreme pressure. Unlike standard VQ series, VQH cores feature reinforced rotors and Bronze-clad Port Plates, engineered to withstand continuous shock loads up to 27.5 MPa (4000 PSI). This selection highlights core OEM-compatible parts including 3G7651 (35VQH), 1U2669 (38VQH), 3G1266 (30VQH), and 3G2746 (25VQH). Utilizing a “drop-in” modular design, maintenance crews can perform on-site core swaps in minutes without disconnecting heavy plumbing, ensuring excavators, loaders, and off-highway trucks return to operation swiftly.

Key Technical Advantages:

• Reinforced Bronze-clad Design: Port plates are engineered with a high-performance bronze alloy coating, providing superior anti-seize properties and self-lubrication under high pressure and temperature.

• Extreme Pressure Durability: Specifically developed for 4000 PSI duty cycles, meeting the rigorous power demands of modern heavy-duty mobile equipment.

• Patented Intra-vane Technology: The vane-within-a-vane structure balances tip loading, significantly reducing stator wear and extending service life by over 30% compared to conventional designs.

• 100% OEM Interoperability: Fully compatible with OEM codes such as 3G7651 and 1U2669, maintaining maximum volumetric efficiency during heavy load cycles.

• Target Applications: Main pumps for heavy excavators, specialized loaders, truck-mounted cranes, off-highway trucks, and high-pressure hydraulic power systems.
