Model code — A10VO85ED72/52R-VSC12K68H
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 | A10VO | A10VO swashplate variable pump (open circuit) |
| Size (NG) | 85 | nominal size NG85 |
| Control | ED72 | electro-hydraulic pressure control |
| Series | 52 | series 52 |
| Rotation | R | clockwise, viewed from the shaft end |
| Seals | V | FKM fluoroelastomer (modern standard) |
| Drive shaft | S | spline, ISO 3019-1 / ANSI B92.1a |
| Mounting flange | C | SAE 2-hole (standard) |
| Work ports | 12 | metric flange seat, fixed metric threads (DIN 13) |
| Through drive | K68 | through drive (coupling and auxiliary pump matching, see §5.3 of the reference) |
| Solenoid connector | — | omitted — none |
| Additional code | H | 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 52, swashplate design for open circuit. Complete model code: A10VO85ED72/52R-VSC12K68H. Size NG85, nominal displacement 85 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: ED72 electrohydraulic pressure control, negative (24 V)
The ED valve is set to a certain pressure by a specified variable solenoid current. When the consumer (load pressure) changes, this causes an increase or decrease in the pump swivel angle (flow) in order to maintain the electrically set pressure level. The pump thus only delivers as much hydraulic fluid as the consumers can take. The desired pressure level can be set steplessly by varying the solenoid current. As the solenoid current signal drops towards zero, the pressure will be limited to pmax by an adjustable hydraulic pressure cut-off (secure fail-safe function in case of power failure, e.g. for fan speed control).
- Negative control: U = 24 V (ED72). Hysteresis: maximum 25 bar.
