Product Description
LIC Hydraulic’s Vickers VQ Series double vane pumps are the industry standard for high-pressure mobile applications. These dual-section pumps (including 2520VQ, 3525VQ, 4525VQ, and 4535VQ) utilize the legendary Intra-Vane technology, which balances hydraulic loading to allow for higher operating pressures and extended service life. We offer 100% Drop-in Interchangeability for configurations like 2520VQ-10A12-1CC-10R. The VQ series is famous for its Modular Cartridge Design, allowing for rapid field repairs without disconnecting hydraulic lines, ensuring your machinery stays productive in mining and construction sites worldwide.
Technical Specifications (Model Breakdown)
Series Models: 2520VQ, 3520VQ, 3525VQ, 4520VQ, 4525VQ, 4535VQ.
Max Operating Pressure: Up to $210\text{ bar}$ ($3000\text{ PSI}$).
Speed Capability: Rated up to $2700\text{ RPM}$.
Technology: Intra-Vane Pumping Element for reduced friction and heat.
Interchangeability: Fully compatible with Eaton/Vickers OEM standards.
Efficiency: High volumetric efficiency maintained throughout the RPM range.
Key Technical Advantages
Intra-Vane Design: By routing pressurized oil under the vanes, the contact force against the cam ring is precisely controlled, minimizing wear and allowing the pump to handle severe pressure spikes.
Dual-Circuit Versatility: Two independent cartridge groups on a single shaft provide simultaneous power for different functions (e.g., steering and lifting) while saving space and PTO ports.
Easy Field Serviceability: The “cartridge kit” concept allows for complete overhauls in minutes. Simply replace the internal rotating group to restore factory-new performance.
Balanced Hydraulic Loading: The dual-chamber design balances the internal radial loads on the bearings, leading to exceptional MTBF (Mean Time Between Failures).
Application Areas
Earthmoving Equipment: Steering and implement circuits for wheel loaders and scrapers.
Mining Machinery: Hydraulic power for haul trucks and drill rigs.
Specialty Vehicles: Compaction power for refuse trucks and heavy-duty lift trucks.
Expert Maintenance Tips
Rotation Direction Verification: Before installing a replacement cartridge kit, double-check that the “V” notch direction matches the rotation of your drive shaft. Incorrect rotation orientation will cause immediate failure.
Initial Priming: Always fill the pump housing with clean hydraulic oil through the inlet port before startup. Running a vane pump “dry” for even a few seconds can score the cam ring.
Inlet Filtration: To prevent vane sticking, ensure the hydraulic system is equipped with high-quality suction strainers and return filters. Maintain an ISO 4406 cleanliness level of 19/17/14.
