Rexroth A11vo190 A11VO95 A11VO130 Hydraulic Piston Pump for Dump Truck
A11VO40, A11VO60, A11VO75, A11VO95, A11VO130, A11VO145, A11VO190, A11VO260 Pump
The A11VO variable axial piston pump of swash plate design for hydrostatic drives in open circuit hydraulic system
- Designed primarily for use in mobile applications.
- The pump operates under self-priming conditions, with tank pressurization, or with an optional built-in charge pump (impeller).
- A comprehensive range of control options is available matching any application requirement.
- Power control option is externally adjustable, even when the pump is running.
- The through drive is suitable for adding gear pumps and axial piston pumps up to the same size, i.e. 100% through drive.
- The output flow is proportional to the drive speed and infinitely variable between qV max and qV min = 0.
- Control devices: LR, LR.C, LR3, LG1, LG2, DR, DRS, DRL, DH1, DH2, DH.D, DH.G, EP1, EP2, DE.D, EP.G, etc.
