Model code — A10VO72DRS/53R-VSD12K15-S
Decoded against the official ordering code of this series (series 53 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) | 72 | nominal size NG72 |
| Control | DRS | pressure and flow control (X-T closed) |
| Series | 53 | series 53 |
| 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 | D | SAE 4-hole |
| Work ports | 12 | metric flange seat, fixed metric threads (DIN 13) |
| Through drive | K15 | 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 A10VO axial piston variable pump, Series 53, swashplate design for open circuit. Complete model code: A10VO72DRS/53R-VSD12K15-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: DRS pressure and flow controller (load-sensing, with flushing)
In addition to the pressure controller function, an adjustable orifice (e.g. directional valve) is used to adjust the differential pressure upstream and downstream of the orifice. This is used to control the pump flow. The pump flow is equal to the actual hydraulic fluid quantity required by the consumer. With all controller combinations, the Vg reduction has priority. The DRS version has no unloading from X to the reservoir; the LS must thus be unloaded in the system. Because of the flushing function of the flow controller in the DRS control valve, sufficient unloading of the X-line must also be provided.
- Basic position in depressurized state: Vg max.
- Setting range up to 250 bar — standard is 250 bar.
- For pressure controller data, see the DR pressure controller.
