A semi-open impeller has a shroud on one side of the vanes, leaving the opposite side exposed. The drawing should identify the shrouded side and the relationship to the surrounding stationary components. The body, hub and blade geometry must remain associated with the selected pump design. Do not classify two versions as different products solely by renaming the same front or rear view.

Provide the intended equipment context, blade geometry and shaft connection. Keep closed, semi-open and open configurations distinct. Flow, head, efficiency and rotational capability require evidence for the exact design and are not established by a product-family name.
Foundry Queen enquiries should include the selected component drawing, quantity and the required delivered condition. Identify the features to be machined, the accessories to be included and the documents needed with the order. This product-family description does not define a stocked model, a universal replacement or an approved performance rating.

When selecting a custom semi-open pump impellers manufacturer, review the actual drawing and the proposed production route. Ask the supplier to identify the included operations and the inspection records agreed for this component. Factory information should relate to that route and the proposed order, rather than an unrelated product or general workshop claim.
The custom semi-open pump impellers price depends on blade arrangement, tooling, material, hub machining and inspection requirements. Compare tooling charges separately from recurring part costs, and keep the drawing revision, quantity and supplied condition consistent between offers. Ask Foundry Queen for a written, specification-based quotation.
Ask the exporter to confirm the agreed packing, reference identification and delivery terms for the destination. Protect the interfaces identified on the component drawing and keep different variants identifiable. Before approval, provide a drawing that clearly shows the exposed and shrouded sides and the mating equipment interfaces.

No universal size, grade or performance value is stated. Define the required configuration and acceptance requirements for the actual drawing-based enquiry.
Yes, include the required specification in the enquiry. The offered manufacturing route and supplied condition must be confirmed in the written quotation.
Compare the related impeller components below by their function and interface requirements. Each image is a product type illustration; the final supplied geometry, material and delivered condition must follow the approved drawing and written quotation. Foundry Queen can review a custom enquiry with the manufacturer, supplier, factory or exporter requirements identified in your purchasing schedule. Price depends on the confirmed specification and order scope.
