Pump Shaft Stainless Profiles
Austenitic and martensitic stainless sections for submersible pump shafts
What Pump Shaft Stainless Profiles Is and Who It Is For
Special profiles for shafts on submersible pumps are produced in both austenitic and martensitic stainless steel. The choice between the two depends on whether the shaft needs maximum corrosion resistance in the pumped fluid or a harder surface where the shaft runs in a bearing or a seal.
Key Benefits
- Both austenitic and martensitic grades available for the same geometry
- Drawn surface reduces the grinding allowance at the bearing journals
- Long drawn bars cut into several shafts with consistent properties
- Stainless throughout, no coating to fail in submerged service
| Materials | austenitic and martensitic stainless steel |
|---|---|
| Standards | ASTM, JIS and EN, 200 to 400 series |
| Cold drawn size tolerance | < 0.05 mm |

| Surface roughness | Ra < 2.5 um |
Who It Is For
- Submersible pump manufacturers
- Water and wastewater equipment builders
- Pump repair and rebuild shops
Problems It Solves
- Coated carbon steel shafts corrode once the coating is damaged
- Grinding stainless from oversized bar is slow and consumes wheels
- Mixed grade shafts behave differently in the same pump range
Technical Features
- Austenitic and martensitic stainless grades
- Round and drawing-defined sections
- Cold drawn tolerance and straightness
- Cut to shaft length

How It Compares
Austenitic grades resist corrosion better in aggressive fluids, martensitic grades take a harder journal surface. We supply both so the pump designer chooses per model rather than per supplier.
Use Guide
- State the pumped medium so the grade can be matched
- Give the journal diameters and the grinding allowance you want left
- Confirm shaft length and keyway requirements

Questions Buyers Ask About Pump Shaft Stainless Profiles
Which stainless grades do you use for pump shafts?
Both austenitic and martensitic stainless steels, selected for the service.
Can you machine the journals as well?
Yes, machining can be added through our CNC machining centre.
Is the surface ready for a mechanical seal?
The drawn surface is Ra below 2.5 um and is normally finished at the seal position by the pump builder.
