INDEPENDENT MODEL-CODE AND SOURCING REVIEW
Danfoss / Sauer-Sundstrand references accepted for structured RFQ review.
Hydrostatic components require machine, loop, charge-system and control information in addition to the nameplate. Legacy Sundstrand references receive an obsolescence check. Published coverage 6 series-level entries

IDENTIFICATION HIERARCHY
How a Danfoss / Sauer-Sundstrand reference moves from a name to a decision
Brand recognition is only the first routing step. The review narrows the inquiry from manufacturer name to product family, series, complete code and finally the installed interfaces and duty.- Brand and aliases Danfoss / Sauer-Sundstrand, Sauer-Danfoss, Sundstrand, Danfoss Power Solutions
- Product family Separate the reference into the relevant valve, pump, motor or service-part group.
- Complete identifier Preserve every suffix, revision, material number and option character visible on the nameplate or document.
- Installed evidence Compare interfaces, operating conditions and application before any replacement statement is released.
SERIES DIRECTORY
Commonly submitted Danfoss / Sauer-Sundstrand references
The table is an inquiry-routing index, not a compatibility chart. Every suffix and installed interface remains subject to review.| Series reference | Product type | Primary review focus | RFQ route |

| Series 45 | Open-circuit piston pumps | Frame, control, shaft and ports | Send full code |
| Series 51 / 90 | Hydrostatic units | Frame, control and charge-system review | Send full code |
| H1 | Hydrostatic pumps and motors | Electronic control and machine integration | Send full code |
| OMM / OMP / OMR | Orbital motors | Displacement, shaft, flange and ports | Send full code |
| PVG | Mobile valve platforms | Sections, actuation, flow and electronics | Send full code |
FAILURE-MODE REVIEW
Why the series rows need different evidence
These checks explain the decision risk behind each published reference. They are review rules, not a claim that every listed configuration is available.| Reference | Mismatch risk | Evidence needed for release |
|---|---|---|
| Series 20 / 40 / 42 | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
| Series 45 | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
| Series 51 / 90 | A shared family label does not prove that the part fits the exact parent assembly or revision. | Parent-unit code, part number, dimensions and supplier confirmation for the stated application. |
| H1 | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
| OMM / OMP / OMR | A similar motor can differ in displacement, speed, shaft load, brake or drain requirements. | Duty data, displacement, mounting, shaft, ports and option comparison. |
| PVG | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |

REVIEW BASIS
Use the manufacturer portfolio to identify the family—not to infer an automatic replacement.
