The fixed-displacement design does not make A2FO selection automatic. Size, series, rotation, shaft, flange and port details still have to match the installation.
Send the complete A2FO reference.: Include the drive speed, pressure, rotation and installation photos.
Model-code review fields
| Field | Why it matters | Evidence |
|---|---|---|
| Nominal size | Sets theoretical displacement and expected flow | Complete code and supplier data |
| Series and pressure rating | Affects permissible operating conditions | Datasheet or quotation record |
| Rotation | Determines correct pumping direction | Nameplate, arrow and drive arrangement |
| Shaft and flange | Controls mechanical fit and torque transmission | Drawing or verified dimensions |
| Ports | Controls hose fit, orientation and case drainage | Port-side photos and connection data |
Application details

Do not release from appearance alone
Two bent-axis pumps can look nearly identical while using different shafts, flange pilots, rotations or port arrangements. The complete record should be approved before purchase.
First-order checks
- Model and quantity against the quotation
- Rotation marking
- Shaft and flange dimensions
- Port type and position
- Packing protection for the shaft and sealing faces
