Bosch Rexroth A4VG Closed Circuit Axial Piston Pump 400 bar
- Closed circuit
- Integrated boost pump
- High pressure 450 bar
Features "Bosch Rexroth A4VG Closed Circuit Axial Piston Pump 400 bar"
The Rexroth A4VG is a variable axial piston pump in swashplate design, specifically engineered for hydrostatic drives in closed circuits. As a high-performance high-pressure pump (up to 450 bar peak), it features an integrated boost pump (charge pump) and the necessary high-pressure relief valves as standard. This makes it the ideal all-in-one solution for travel drives in mobile machinery.
Function and Benefits:
- Nominal sizes from 28 to 125 cm³/rev
- High nominal pressure of 400 bar (peak 450 bar) for maximum power density
- Integrated auxiliary pump for boost and pilot oil supply
- Flow direction changes by swiveling through the zero position
- Includes high-pressure relief valves with integrated boost function
- Standard with adjustable pressure cut-off
- Compact design due to integration of many valve functions
Applications:
- Travel drives (e.g., wheel loaders, dumpers, forklifts)
- Road construction machinery (rollers, pavers)
- Agricultural harvesters
- Forestry machinery
