Impeller Types and Blade Designs

Your impeller may have open blades, a supporting back plate, or enclosed flow passages. These examples help identify the general form; the blade geometry, dimensions, and shaft connection follow your equipment design.

Open Impellers

Exposed blades extend from the central hub. YTD casts the blade layout in your design and machines the bore or other shaft connection for the assembly.

Semi-Open Impellers

A back plate supports the blades while the front remains open. We cast the blades, plate, and hub together, then machine the faces and shaft features that fit adjoining parts.

Get a Quote

Closed & Enclosed Impellers

Front and back covers enclose the blades to form internal flow passages. Investment casting creates this geometry as one part, followed by machining of the bore, sealing faces, and mounting features.

Radial, Mixed & Axial Designs

Radial, mixed-flow, and axial arrangements move the medium in different directions. YTD manufactures the vane geometry and hub defined for your equipment.

Impeller Casting Materials

The medium, operating temperature, and exposure to corrosion or wear all affect material choice. YTD can work with your specified grade or help compare options for the conditions the impeller will face.

Stainless Steel

For water, chemical, marine, and other corrosive service, YTD casts a range of stainless steel grades. We help match the grade to the medium, temperature, and level of corrosion resistance your project requires.

Carbon & Alloy Steel

Carbon and alloy steels provide different combinations of strength, toughness, and wear resistance. We coordinate the steel grade and heat treatment around the mechanical requirements of your impeller.

Aluminum Alloys

Aluminum alloys suit equipment where rotating mass or overall weight matters. YTD supplies the casting, machining, and required surface finishing in one order, ready for your assembly process.

High-Temperature Alloys

For hot service, nickel-, cobalt-, and iron-base alloys help retain strength and stability at elevated temperatures. YTD combines alloy casting with the heat treatment and machining required for the finished impeller.

What You Can Customize

Your drawing defines how the impeller moves the medium and fits the assembly. YTD carries those requirements through the casting and finishes the interfaces that need closer dimensional control.

Blade Shape & Layout

Set the vane count, angle, curvature, and flow passages for your design. Investment casting forms complex vanes and the hub together, reducing the amount of geometry that must be cut from solid metal.

Hub & Shaft Connection

Specify the bore, keyway, threads, and locating surfaces that connect the impeller to your shaft. We cast the body and machine these interfaces as part of the same order.

Size & Fitting Surfaces

The outside diameter, overall width, and mounting dimensions follow your assembly envelope. We finish-machine the faces and fits that need closer control for installation.

Finishing & Inspection

Add the heat treatment, surface finish, dimensional checks, and material tests your project needs. YTD coordinates them with casting and machining and provides the agreed inspection records for review.

Have an Impeller Drawing or Sample?

Send your drawing, model, or sample details. Tell us what the impeller moves, where it fits, and any material, quantity, or inspection requirements you already know. We will turn that information into a manufacturing proposal and quote.

Investment Casting and CNC Machining for Impellers

Silica-sol investment casting forms curved vanes, the hub, and complex flow passages close to their finished shape. This reduces the amount of material that must be removed compared with machining the complete geometry from solid stock.

Precision machining then finishes the bore, keyway, mounting faces, and sealing faces that control how the impeller fits the assembly. YTD also coordinates heat treatment, surface finishing, inspection, and packing, giving you one point of contact through delivery.

You do not need to choose the complete manufacturing route before contacting us. Send the part and the requirements you already know, and we will propose how to make it and explain what the quotation includes.

Dimensional Inspection and Material Testing

The shaft bore, mounting faces, and other critical dimensions affect how the impeller fits your assembly. The alloy and any heat treatment affect whether the finished part meets your material specification. We inspect the agreed features and provide the records required for your review.

Available testing includes material composition, tensile strength, hardness, CMM measurement, fluorescent penetrant testing, X-ray inspection, and salt-spray testing. The inspection plan focuses on the dimensions, material properties, and surface requirements you need to verify.

If balance is critical to the application, include the operating speed, balance requirement, and required report with your enquiry so they can be considered in the manufacturing proposal.
