Picture

Please could add somebody a picture or a painting of the prinzipe or a model? --138.89.56.7 13:10, 12 May 2006 (UTC) Dieter

Impellers without pressure increase

I've worked in industries that used parts called impellers in sensor set ups. This may have been a case of them calling a part by a name that should have been something else as far as linguists are concerned. Nevertheless, it is quite common and I think we need to revise the first sentence of this article accordingly. Alternatively we should at least add an "other uses" paragraph. 71.236.24.129 (talk) 04:29, 10 May 2009 (UTC)

I think that such a part would more appropriately be called a turbine or a runner since it is driven by the flow of the fluid and does not impart motion. See also my comment regarding the picture of a runner that I view as inappropriate. It may be worth writing a paragraph concerning this misapplication of 'impeller' and directing readers to the appropriate article.Leofric1 (talk) 06:44, 19 May 2009 (UTC)

Turbine Runner

The picture of a runner for a turbine at a dam is inappropriate. It's a runner, not an impeller. Force is transmitted by the water to the axle in a turbine, as opposed to vice-versa in a pump. Leofric1 (talk) 07:24, 13 May 2009 (UTC)

Yes, it is wrong! please remove the picture which is totally misleading! thx — Preceding unsigned comment added by 193.49.249.136 (talk) 08:48, 4 January 2022 (UTC)

14 years later and neither one of you, or anyone else, could be bothered to fix this? GA-RT-22 (talk) 22:33, 8 May 2023 (UTC)

Impeller Pitch

Anyone knows the difference between square and steep pitch (super pitch)? --rolandog (talk) 17:25, 28 May 2009 (UTC)

Lily impeller

Would someone knowledgeable please include information on the lily impeller invented by Jay Harmon? (fotoguzzi)76.105.160.69 (talk) 23:30, 30 November 2010 (UTC)

Is it notable? Is there anything special about that shape (except looking pretty)? If not it should not be included. 78.82.232.101 (talk) 15:29, 11 September 2020 (UTC)

Deleted section

I deleted the section describing how they "replaced the axial compressor on X turboprop with an impeller", because an axial compressor IS an impeller! What he means is that they replaced the axial type of compressor with a centrifugal compressor. They are BOTH impellers, so what difference does it make if they replaced one with the other? Author probably read somewhere how they "used a centrifugal impeller" in the new engine, and got confused, thinking that must mean that it's an impeller, unlike an axial compressor. But its not; they are both impellers, and thus the whole section has no relevance, as well as being misleading to people..45Colt 10:14, 12 November 2015 (UTC)

Impeller vs turbine?

Is not the following contradicting information? Please could someone with relevant knowledge look at this: First sentence of wiki page: "An impeller or impellor[1] [...] is the opposite of a turbine [...]." vs Section In agitated tanks: "Impellers can be further classified [...] into [...] sub-types: [...] Turbines" — Preceding unsigned comment added by 188.151.132.6 (talk) 16:11, 27 August 2021 (UTC)

I also find this confusing. Sources across the internet refer to turbines as a subset of impellers. Autumn astronomer (talk) 04:57, 16 May 2025 (UTC)
