Product overview
New aftermarket A10VSO axial piston variable pump, Series 31, swashplate design for open circuit. Complete model code: A10VSO28DFE1/31R-PKC62N00. 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: DFE1 electronic pressure and flow control
The pressure and output flow of the pump are controlled electronically by means of a proportional valve. The output flow is controlled by varying the swivel angle of the pump. Variations in pump speed — e.g. with a diesel engine drive — are not taken into consideration. The pump pressure and position are fed back via a pressure sensor and an inductive positional transducer to the amplifier card which is necessary to the control. The DFE1 model pump is suitable for control applications in conjunction with the analogue amplifier card VT 5041.
- Controller data: hysteresis < 1% of Vg max; repeatability < 1%; pilot oil consumption approx. 2.5 l/min max.
- The amplifier card and the pressure sensor are supplied separately.
- For safety reasons an additional pressure relief valve should be mounted near to the pump pressure control system, to ensure that the maximum permissible operating pressure is not exceeded.
