What needs to be clarified
Assess the pump operating description, compare fluid direction with the impeller axis, and review technical support for the proposed classification approach to that model.
Materials to prepare
- Report with proposed classification reasoning and pump images
- Casing sections, impeller drawing and model-specific manual
- Technical passport, manufacturer marking and actual shipment configuration
What to compare
Distinguish displacement and dynamic operation, then compare impeller inlet/outlet flow with its axis. Check guide vanes, stages and internal direction changes. Link drawings to the marked model; motor power and external outlet bends are not independent evidence of flow type.
Possible outcome of the analysis
An annotated flow diagram and verified-feature table may support the description or show that clarification is needed before it is used in shipment classification materials.
Limits of the conclusions
Review assigns no official code and guarantees no customs decision. Related-model properties require verification; heading texts and notes must match the declaration date.
