Investment-Cast Stainless Steel Pump Impeller

An impeller item for a rotating pump assembly. This pump impeller is specified in Stainless Steel. The manufacturing specification includes investment casting and precision machining.

Technical Overview

• Part: Pump Impeller
• Material: Stainless Steel
• Processing: Precision Machined, Investment-Cast

Pump Impeller Design and Assembly

• Vane and rim geometry: show the flow-related profile, outside diameter and direction of rotation.
• Hub connection: define the shaft bore, keyway or other attachment features present in the design.
• Assembly controls: specify clearances, reference datums and any balance requirement separately.

Material and Manufacturing Requirements

The specified material is stainless steel. State the exact grade and delivery condition when requesting a quotation, particularly where the material must match an existing assembly or a defined service requirement.

Investment casting is included in the specified route. Identify which features remain as cast and which require finishing so the casting requirements and final assembly dimensions can be reviewed together.

Precision machining is specified for this component. Identify the critical dimensions, their reference datums and the surfaces requiring a defined finish so the quotation reflects the functional requirements of the actual part.

Quotation Information

Provide the vane geometry, outside diameter, hub bore and shaft attachment. Balance requirements and rotation direction should be stated for the final part. Include the drawing revision, required quantity and any sample or inspection documentation needed for approval.
