Variable Displacement axial Piston Pump
Model AA4VG
Variable Displacement Axial Piston Pump
Closed circuit
Sizes 28 . . . 250
Series 3
Nominal pressure 5800 PSI
Peak pressure 6500 PSI
Features
- Variable displacement axial piston pump of swashplate design for hydrostatic closed circuit transmissions
- Flow is proportional to drive speed and displacement and is infinitely variable
- Output flow increases with swivel angle from 0 to its maximum value
- Swivelling the pump over center smoothly changes the direction of flow
- Availability of a highly adaptable range of control and regulating devices
- The pump is equipped with two pressure relief valves on the high pressure ports to protect the hydrostatic transmission (pump and motor) from overloads

Bosch Rexroth – AA10VG Axial Piston Pump
Model AA10VG
Variable Displacement Axial Piston Pump
Series 10, Size 18 . . . 63
Nominal pressure 4350 psi (300 bar)
Peak pressure 5100 psi (350 bar)
Closed circuit
Features
- Variable axial piston pump of swashplate design for hydrostatic closed circuit transmission
- Flow is proportional to drive speed and displacement and is infinitely variable
- Output flow increases with the swivel angle of the swashplate from 0 to its maximum value
- Flow direction changes smoothly when the swashplate is moved through the neutral position
- A wide range of highly adaptable control devices is available for different control and regulating functions
- The pump is equipped with two pressure relief valves on the high pressure ports to protect the hydrostatic transmission (pump and motor) from overload
- The pressure relief valves also function as boost valves
- The integrated boost pump acts as a feed and control oil pump
- The maximum boost pressure is limited by a built-in boost pressure relief valve
