A11VO comparison record
| Parameter group | Original data to capture | Release requirement |
|---|---|---|
| Hydraulic | Displacement, nominal and peak pressure, speed | Candidate data supports the operating range |
| Control | Complete control code, signal and setting range | Control behavior is confirmed, not inferred |
| Mechanical | Rotation, flange, shaft and installation envelope | Drawing or measured dimensions are reviewed |
| Connections | Main ports, case drain, pilot ports and orientation | Every connection is mapped before shipment |
| Options | Through-drive, auxiliary pump and special suffixes | Option is confirmed or listed as unavailable |
Information needed from the machine
- Machine manufacturer, model and year
- Original pump nameplate and order number
- Working and peak pressure
- Expected flow or drive speed
- Control signal and commissioning information
- Reason for replacement and failure symptoms
Common A11VO replacement risks
- A similar displacement with a different controller can change machine response
- A shaft or flange difference can prevent installation
- Port orientation can conflict with hoses or the machine frame
- Incorrect rotation can damage a pump during startup
- Through-drive and auxiliary functions may be hidden in suffixes
Recommended release route
- Decode the complete reference
- Compare the supplier drawing and technical data
- Record every known difference on the quotation
- Confirm inspection evidence before dispatch
- Use controlled commissioning for a first order or higher-risk machine
