Product overview
New aftermarket A10VNO axial piston variable pump, Series 53, swashplate design for open circuit. Complete model code: A10VNO85EK1DS/53R-VSD46N00P-S4683. Size NG85, nominal displacement 85 cm³/rev. Nominal pressure 210 bar, maximum pressure 250 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: EK1DS electro-proportional pressure and flow control with controller cut-off, 12 V
Based completely on the EP variant, the EK version additionally integrates a controller cut-off in the electric characteristic curve: if the pilot signal is lost (e.g. cable break), the pump swivels to Vg max and then works with the DRF settings if necessary. The controller cut-off is intended for short-term use only. A PWM signal controls the solenoid.
- U = 12 V (EK1DS). Minimum working pressure 50 bar.
Other control options on this size
This 85 cm³ Series 53 pump is also available with other controls:
