Not Just Stronger. Smarter. The A4VBO Takes High-Pressure Pumping to the Next Level
For decades, engineers designing high-pressure hydraulic circuits defaulted to a trusted workhorse: the Bosch Rexroth A4VSO. Its reputation was built on millions of hours of reliable performance. But what happens when applications demand even more? When pressures climb, control needs to be more precise, and power density becomes critical?
You don't replace a legend. You evolve it.
Introducing the Bosch Rexroth A4VBO, the robust and reliable evolution of the proven A4VSO design, purpose-built for the demands of modern high-pressure systems.
Built on a Foundation of Trust
The A4VBO isn't a radical departure; it's a focused advancement. We took the core principles that made the A4VSO an industry standard—its durability, its swashplate design, its fundamental reliability—and engineered them for a new level of performance. This means you get the field-proven DNA of the A4VSO, now optimized to excel in today's most demanding open-circuit applications.
Optimized for High Pressure (Up to 450bar)
"High pressure" isn't just a number on a datasheet. It's a demanding environment that exposes every weakness in a component. The A4VBO was specifically designed to thrive in this environment.
- Robust Rotary Group: The heart of the pump, the axial piston rotary group, has been strengthened and optimized to handle the immense forces generated at nominal pressures of 450 bar and peak pressures of 500 bar.
- High Power Density: By delivering more power from a compact frame, the A4VBO allows for more efficient machine design, saving valuable space and weight without sacrificing performance.
- Long Service Life: The robust design, including optimized bearings and internal flushing capabilities, ensures the A4VBO delivers a very long service life, even under continuous high-pressure operation. This translates to more uptime, lower maintenance costs, and a better total cost of ownership.
The Digital Advantage: Precision Control When it Matters
Raw power is only useful if it can be controlled. The A4VBO integrates seamlessly with Rexroth's advanced digital electronic control systems, like the HS5, transforming a powerhouse pump into a precision instrument.
What does this mean for your application?
- Electric Displacement & Pressure Control: The HS5 option provides continuous, highly accurate control over displacement and pressure. This allows for precise load matching, improved efficiency, and sophisticated machine cycles.
- Torque Limitation: Protect your entire drivetrain. The digital control option can actively limit torque, preventing overloads and protecting the motor and other system components.
- Seamless System Integration: With modern digital controls, the A4VBO becomes a communicative part of your larger control architecture, ready for the monitoring, diagnostics, and performance demands of Industry 4.0.
The A4VBO: The Go-To Pump for Demanding Applications
With its combination of proven reliability, high-pressure capability, and intelligent control, the A4VBO is the ideal solution for applications such as:
- Large Industrial Presses: Where immense, controllable force is paramount.
- Marine & Offshore Equipment: Demanding reliability and power in harsh environments.
- Heavy-Duty Mobile Machinery: Requiring high power density and robust construction.
- Advanced Test Benches: Needing precise and repeatable pressure and flow control.
Evolve Your Power
The A4VBO represents the next step in high-pressure hydraulic power. It honors the legacy of the A4VSO by building upon it, delivering a pump that is not just stronger, but smarter, more controllable, and ready for the future of industrial and mobile hydraulics.
