Model code — A10VNO45ED72/52L-VRC17K52-S
Decoded against the official ordering code of this series (series 52 uses 12 positions, in the order of positions 02–13 of series 31). This unit reads as follows:
| Field | Value | Meaning |
|---|---|---|
| Axial piston unit | A10VNO | A10VNO swashplate variable pump (open circuit) |
| Size (NG) | 45 | nominal size NG45 |
| Control | ED72 | electro-hydraulic pressure control |
| Series | 52 | series 52 |
| Rotation | L | counter-clockwise, viewed from the shaft end |
| Seals | V | FKM fluoroelastomer (modern standard) |
| Drive shaft | R | spline, high torque |
| Mounting flange | C | SAE 2-hole (standard) |
| Work ports | 17 | see the port matrix in the reference — we confirm before shipping |
| Through drive | K52 | through drive (coupling and auxiliary pump matching, see §5.3 of the reference) |
| Solenoid connector | — | omitted — none |
| Additional code | -S | special version / customer code — not detailed per case in the reference; we confirm it against the order |
Product overview
New aftermarket A10VNO axial piston variable pump, Series 52, swashplate design for open circuit. Complete model code: A10VNO45ED72/52L-VRC17K52-S. Size NG45, nominal displacement 45 cm³/rev. Nominal pressure 210 bar, maximum pressure 250 bar. Direction of rotation L (counter-clockwise, viewed on the drive shaft). Quality checked before shipping. Contact us to confirm exact configuration and availability before ordering.
Control: ED72 electrohydraulic pressure control, negative control (24 V)
The ED valve sets a certain pressure according to a specified variable solenoid current; as the load pressure changes, the pump swivel angle (flow) is adjusted to maintain the electrically set pressure level. The desired pressure level can be set steplessly by varying the solenoid current. If the current signal drops towards zero, the pressure is limited to pmax by the adjustable hydraulic pressure cut-off (fail-safe in case of power loss).
- Negative control: U = 24 V (ED72). Hysteresis: maximum 25 bar.
