Product and Interface Review
Impeller geometry should include diameter, vane profile, rotation direction, inlet and outlet dimensions, shaft interface and reference datums. Operating speed and balance criteria are needed for process planning. AODSON reviews castability and machining access but does not independently change hydraulic geometry or claim system performance without customer validation.
Key Manufacturing Features
- Support for multiple customer-designed impeller types
- Corrosion-resistant stainless and duplex alloys
- CNC bore, keyway and reference-face machining
- Runout and balance inspection to agreed criteria
Materials, Manufacturing and Surface Finish
Wax tooling and ceramic shell investment casting reproduce the hub, vanes and shrouds as one component. Process planning addresses blade filling, internal passage access and section transitions. CNC machining finishes the shaft connection, while optional blade finishing and balance inspection follow the approved specification.
The proposed route for this custom pump impeller casting program is Investment casting, shaft-interface machining, blade finishing and balance inspection. Final material, tolerances, finish and testing remain subject to the approved drawing and purchase specification.
Typical Applications
- Industrial centrifugal pumps
- Chemical and water-treatment pumps
- Marine circulation equipment
- OEM pump replacement programs
Quality Control and Approval
Quality controls can include material certification, visual and surface inspection, dimensional reports, bore and keyway checks, runout and the specified balance condition. Hydraulic efficiency, head and cavitation performance depend on the complete pump design and are validated by the pump manufacturer.

Frequently Asked Questions
Can this custom pump impeller casting program be customized?
Yes. Geometry, interfaces, material, finish and inspection can be produced from an approved drawing or sample. Feasibility is reviewed before quotation or tooling.
Which material grades are available?
The current range is 304, 316, duplex or customer-specified corrosion-resistant casting alloy. Final selection should consider corrosion, strength, temperature, wear, conductivity and applicable customer standards.
What is needed for an accurate quotation?
Please provide geometry, material, quantity, critical tolerances, finish and delivery requirements. Describing the application helps engineering identify risks that may not be visible on the drawing alone.
