Product and Design Review
At smaller diameters, blade thickness, edge completeness and bore concentricity become especially important. AODSON reviews minimum sections, machining allowance and inspection methods before tooling. Medical or regulated use is not inferred from size; any regulatory or cleanliness requirement must be stated explicitly.
Key Manufacturing Features
- Compact open-vane geometry
- Backward-curved blade profile
- Machined central bore option
- Custom size for drawing-based equipment
Materials, Manufacturing and Surface Finish
Precision casting produces the hub, blades and supporting geometry as one stainless component. CNC machining controls the shaft interface and reference faces. Blade finishing, runout and balance inspection are planned from approved geometry, rotational speed and customer acceptance criteria.
For this small open pump impeller, the proposed route is Silica sol investment casting, bore machining and balance inspection. Final material, finish and testing remain subject to the approved drawing and service conditions.
Typical Applications
- Compact centrifugal pumps
- Dosing and circulation equipment
- Laboratory fluid systems
- Small OEM pump assemblies
Quality Control and Approval
Quality checks can include material verification, blade completeness, key dimensions, bore and keyway geometry, runout and the specified balance condition. Hydraulic or aerodynamic performance remains the equipment manufacturer’s responsibility because it depends on the complete system and operating point.

Frequently Asked Questions
Can this small open pump impeller be customized?
Yes. Geometry, mounting interfaces, material, finish and inspection can be manufactured from an approved drawing or sample. Feasibility is reviewed before quotation or tooling.
Which material grades are available?
The current recommendation is 316L or another stainless alloy selected for the handled liquid. Final selection should consider corrosion, strength, temperature, wear 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.
