Rexroth A11VO Hydraulic Pump

The A11VO is a variable pump with axial piston rotary group in swashplate design for hydrostatic drives in open circuits. The flow is proportional to the drive speed and the displacement. The flow can be continuously changed with closed loop control.

Features:

1) Variable axial piston pump of swashplate design for hydrostatic drives in open circuit hydraulic system.

2) Designed primarily for use in mobile applications.

3) The pump operates under self-priming conditions, with tank pressurization, or with an optional built-in charge pump (impeller).

4) A comprehensive range of control options is available matching any application requirement.

5) Power control option is externally adjustable, even when the pump is running.

6) The through drive is suitable for adding gear pumps and axial piston pumps up to the same, i.e. 100% through drive.

7) The output flow is proportional to the drive speed and infinitely variable between qV max and qV min = 0.

Type: A11VO40, A11VO60, A11VO75, A11VO95, A11VO130, A11VO145, A11VO190, A11VO260
