Product Description
LIC Hydraulic proudly presents the Vickers VQ Series, the high-performance heart of global mobile hydraulic systems. Designed for heavy-duty applications, these pumps utilize Intra-Vane technology to minimize tip-to-stator friction, ensuring a volumetric efficiency of over $90\%$. The 25VQ17A and its counterparts feature a unique Cartridge Kit design, allowing for rapid field servicing without disconnecting the pump from its drive shaft—keeping your machinery on the move.
Key Technical Features
Intra-Vane Technology: Automatically balances the forces on the vanes, providing better tracking and sealing at high pressures while reducing wear on the cam ring.
Fast Field Service: The cartridge kit can be replaced in minutes, offering a cost-effective alternative to full pump replacement.
High Volumetric Efficiency: Maintains consistent flow and pressure even as oil temperature rises, critical for precise control of booms and loaders.
Buna-N or Viton Seals: Available with various sealing options to accommodate different hydraulic fluids and extreme temperature ranges.
Expert Maintenance Tips
Rotation Check: Before installing a new cartridge kit, verify the direction of rotation (Clockwise or Counter-Clockwise). Most VQ pumps are not reversible without changing the internal cartridge orientation.
Inlet Filtration: Vane pumps are highly sensitive to “silt” and fine contamination. Maintain filtration at ISO 4406 19/17/14 to prevent the vanes from “sticking” in their slots.
Cold Start: In low-temperature environments, allow the pump to idle without load for 5 minutes. Cold, thick oil can cause vane chatter and damage the cam ring.
