INDEPENDENT MODEL-CODE AND SOURCING REVIEW
Bucher Hydraulics references accepted for structured RFQ review.
Bucher reviews separate standard product families from configured power units and manifold solutions; custom blocks require a circuit and interface record.
PRODUCT COVERAGE
What can enter the review process
CATEGORY ROUTES
Review Bucher Hydraulics references by product category
Start from the product category that matches the installed component, then submit the complete model code.
IDENTIFICATION HIERARCHY
How a Bucher Hydraulics 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 aliasesBucher Hydraulics, Bucher
- Product familySeparate the reference into the relevant valve, pump, motor or service-part group.
- Complete identifierPreserve every suffix, revision, material number and option character visible on the nameplate or document.
- Installed evidenceCompare interfaces, operating conditions and application before any replacement statement is released.
PRODUCT AND REPLACEMENT ROUTES
Bucher pump and valve RFQ routing
Bucher hydraulic pump and valve references are reviewed by full code, displacement or function, mounting, ports and application.
SERIES DIRECTORY
Commonly submitted Bucher Hydraulics 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 |
|---|---|---|---|
| AP | External gear pumps | Group, displacement, flange, shaft and valves | Send full code |
| QX / QXM | Internal gear pumps and motors | Size, rotation, mounting and pressure duty | Send full code |
| UP | Compact power packs | Motor, pump, reservoir and circuit | Send full code |
| Cartridge valve families | Screw-in and slip-in valves | Cavity, function, pressure and actuation | 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 |
|---|---|---|
| AP | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
| QX / QXM | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
| UP | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
| Cartridge valve families | The valve may mount but produce the wrong function, response or electrical behavior. | Code breakdown, hydraulic function, interface drawing and electrical data. |
