Model code — A4VSO40DFR/10R-PZB13K68
Decoded position by position against the RE 92050 model code table (14 positions). Positions 09–14 form one continuous options string without separators; this unit reads as follows:
| Position | Value | Meaning |
|---|---|---|
| 01 Hydraulic fluid | — | omitted — mineral oil + HFD |
| 02 Unit | A4VS | swashplate variable pump (350 bar nominal / 400 bar peak) |
| 03 Boost pump | — | omitted — no boost pump (L only on NG750) |
| 04 Mode | O | open circuit |
| 05 Size (NG) | 40 | nominal size NG40 |
| 06 Controller | DFR | pressure and flow control (X-T open) |
| 07 Design series | 10 | Series 1x (NG40 / 71) |
| 08 Rotation | R | clockwise, viewed from the drive shaft end |
| 09 Seal material | P | NBR body with PTFE shaft seal (for HFA / HFB / HFC) |
| 10 Drive shaft | Z | spline shaft, DIN 5480 |
| 11 Mounting flange | B | ISO 3019-2 metric 4-hole (NG40–500) |
| 12 Work ports | 13 | standard: SAE flange on B/S side, 90°, metric threads |
| 13 Through-drive flange | K68 | SAE J744 or ISO 3019-2 metric through drive: K68 |
| 14 Filtration | — | omitted — no filter |
Note: P in position 09 is a seal code, while P in position 10 is a straight key shaft — the same letter has two different meanings. H in position 11 is the ISO 3019-2 eight-hole flange (NG500 / 750 / 1000).
Product overview
New aftermarket A4VSO40DFR/10R-PZB13K68 axial piston pump. Swashplate-type variable displacement pump for open circuit, from the A4VSO Series 10/11/30 family. Size NG40, geometric displacement 40 cm3/rev.
Nominal pressure 350 bar, peak pressure 400 bar. Maximum drive speed 2600 rpm at Vg max; flow approx. 60 L/min at 1500 rpm.
This listing covers the A4VSO 40 DFR version. Supply is as a new aftermarket replacement unit, quality checked before shipping. Because the full model code defines mounting, seals, shaft and ports, please send us your complete nameplate code before ordering and we will confirm the exact configuration.
Control: DFR pressure-flow controller
The DFR control combines pressure limitation with flow matching (load-sensing). In the basic position flow is delivered at pump pressure; when no flow is needed, the pump swivels back to reduce losses.
