Rexroth A15VSO Series Hydraulic Pump | A15VSO280 A15VSO175 | E2CHV Control

LIC Hydraulic provides the Rexroth A15VSO Series, the premium choice for high-pressure industrial hydraulic power units. Engineered for open-circuit systems, the A15VSO series—including the high-capacity A15VSO280, A15VSO175, and A15VSO210—is built for relentless duty cycles. Featuring the sophisticated E2CHV electronic proportional control, these pumps deliver surgical precision in displacement and pressure regulation. With a continuous pressure rating of $350\text{ bar}$ and a peak of $420\text{ bar}$, the A15VSO280 ensures that your heavy-duty presses and metallurgical machinery operate with maximum energy efficiency and dynamic responsiveness.

Technical Highlights

• Superior Self-Priming Speed: Optimized suction port and cylinder geometry allow for higher operating speeds without the risk of cavitation.

• Electronic Proportional Control (E2): Integrated electronic feedback for closed-loop control of swashplate angle, ensuring high linearity and minimal hysteresis.

• Robust Swashplate Design: Engineered to handle massive axial and radial forces, significantly extending the MTBF (Mean Time Between Failures) in high-pressure applications.

• Modular Control Options: Whether you require pressure cut-off, load sensing, or electric-proportional control, the A15VSO series offers a flexible platform for any industrial logic.

Application Areas

• Heavy Presses: Forging, extrusion, and multi-axis stamping lines.

• Steel & Mining: Primary power for continuous casters and heavy material handling systems.

• Industrial HPUs: Centralized hydraulic systems for factories requiring stable, high-pressure flow.

Expert Maintenance Tips

• Mandatory Priming: Due to its large displacement, the A15VSO280 must be fully pre-filled with clean hydraulic oil through the highest case drain port before startup.

• Monitor Electrical Connectors: Ensure the solenoids and feedback sensors are protected from vibration and moisture to maintain the accuracy of the E2 control logic.

• Filtration Standard: To protect the precision-engineered piston group, maintain a fluid cleanliness level of ISO 18/16/13 or better. Particle contamination is the primary cause of swashplate “scoring.”
