Product overview
New aftermarket A10VSO axial piston variable pump, Series 31, swashplate design for open circuit. Complete model code: A10VSO28DFLR/31R-VSA12N00. Size NG28, nominal displacement 28 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: DFLR pressure, flow and power controller
Pressure controller equipped like DR; equipment of the flow controller like DFR1. In order to achieve a constant drive torque with varying working pressures, the swivel angle and with it the output flow from the axial piston pump is varied so that the product of flow and pressure remains constant. Flow control is possible below the power control curve.
- Please contact us regarding beginning of control at less than 50 bar.
- When ordering please state the power characteristics to be set at the factory in plain text, e.g. 20 kW at 1500 rpm.
