Rexroth A4V / A4VG Pump
The Bosch Rexroth A4VG Series 60 is a high-pressure, swashplate-design axial piston pump. It’s widely regarded as a "workhorse" in mobile hydraulics (like loaders or excavators) due to its reliability and high power density. In axial piston variable pumps, the flow is proportional to the drive speed and the displacement. The flow can be steplessly changed by adjusting the swivel angle. Axial piston variable pumps are available for hydrostatic drives in open and closed circuits.
- Integrated Boost Pump: Features an internal charge pump to maintain circuit pressure and prevent cavitation, simplifying your system layout.
- High Power Density: Exceptional power-to-weight ratio allows for high torque output in tight machine envelopes.
- Bi-Directional Control: The swashplate swivels "over-center," reversing the flow direction without the need for complex external valves.
- Safety First: Built-in high-pressure relief valves protect your transmission from sudden load spikes and pressure surges.
- Precision Controls: Available with EP (Electric Proportional), HW (Manual Servo), and DA (Automotive Speed-Related) control modules.
