Product Description
The Vickers V Series (including 2520V, 3525V, 4535V, and 20V) from LIC Hydraulic is the global standard for High-Performance Intra-Vane Hydraulic Pumps. Designed for both industrial and mobile applications, these pumps are renowned for their high efficiency and industry-leading noise reduction. We offer both single pumps and double pump configurations that provide 100% mechanical interchangeability with original Vickers/Eaton units. Every unit and cartridge kit undergoes 100% simulated load testing to guarantee peak volumetric efficiency and reliability in high-cycle operations.

Housing: High-strength cast iron with drop-in cartridge design
Mounting: SAE Standard Flanges
Key Technical Advantages
Intra-Vane Technology: By balancing the pressure forces acting on the vanes, this design reduces the tip-to-stator friction. This allows for continuous operation at $2500\text{ psi}$ with minimal heat generation and wear, extending service life significantly.
Modular Cartridge Design: The internal “cartridge kit” (comprising the rotor, vanes, cam ring, and side plates) can be replaced as a single unit. This allows for rapid field servicing without disturbing the pump’s connection to the main hydraulic lines.
Dynamic Flow Logic (Double Pumps): Double pumps like the 4535V allow for two separate hydraulic circuits or combined flow for rapid actuator movement. This flexibility is critical for machines requiring both high-speed positioning and high-pressure clamping.
Ultra-Low Noise Operation: The precision-timed ports and smooth vane engagement provide a quiet, stable output, making V series pumps the ideal choice for indoor manufacturing and noise-sensitive environments.
Application Areas
Plastics & Die Casting: Primary power source for injection molding machines and high-pressure clamping units.
Rubber & Metal Forming: Powering hydraulic presses, balers, and vulcanizing equipment.
Mobile Auxiliary Systems: Steering and pilot control circuits for harvesters, sweepers, and road compactors.
Factory Automation: Centralized hydraulic power units (HPUs) for large-scale assembly lines.
Expert Maintenance Tips
Maintain Minimum RPM: These pumps require centrifugal force to seat the vanes against the cam ring. Ensure the motor speed remains above $600\text{ RPM}$ to avoid internal flow ripples and premature ring wear.
Monitor Inlet Vacuum: Vane pumps are highly sensitive to cavitation. Ensure the suction line is large enough and filters are clean; a “screeching” noise is a definitive sign of air ingress or vacuum starvation.
Cartridge Orientation: When replacing a cartridge kit, pay close attention to the rotation arrows. Installing a clockwise (CW) cartridge in a counter-clockwise (CCW) housing will cause immediate failure upon startup.
