Product overview
New aftermarket A10VSO axial piston variable pump, Series 31, swashplate design for open circuit. Complete model code: A10VSO140DG/31R-VSB12N00. Size NG140, nominal displacement 140 cm³/rev. Nominal pressure 280 bar, maximum pressure 350 bar. Direction of rotation R (clockwise, viewed on the drive shaft). Quality checked before shipping. Contact us to confirm exact configuration and availability before ordering.
Control: DG two-point control, direct operated
The variable pump can be set to a minimum swivel angle by connecting an external switching pressure to port X. This will supply control fluid directly to the stroking piston; a minimum control pressure of pst ≥ 50 bar is required. The variable pump can only be switched between Vg max and Vg min. The required switching pressure at port X is directly dependent on the actual working pressure pB in port B. The maximum permissible switching pressure is 280 bar.
- Switching pressure pst in X = 0 bar → Vg max.
- Switching pressure pst in X ≥ 50 bar → Vg min.
