| Additional code | -S | special version / customer code — not detailed per case in the reference; we confirm it against the order |
Product overview
New aftermarket A10VO axial piston variable pump, Series 53, swashplate design for open circuit. Complete model code: A10VO72LA9DS/53R-VSD46N00-S. Size NG72, nominal displacement 72 cm³/rev. Nominal pressure 250 bar, maximum pressure 315 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: LA9DS pressure, flow and power controller (power limiter)
Pressure controller equipped as DR(G); the flow controller part is equipped like DRS (DFR1). To achieve a constant drive torque with varying working pressures, the swivel angle and with it the volume flow of 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.
- Beginning of control: LA5 10–35 bar / LA6 36–70 bar / LA7 71–105 bar / LA8 106–140 bar / LA9 141–230 bar (nominal drive torque at that point).
- Pilot fluid consumption: max. approx. 5.5 l/min.
- When ordering, please state the power characteristics to be set at the factory in plain text, e.g. 20 kW at 1500 rpm.
