Low shear?

I would consider diaphragm pumps as high shear. —Preceding unsigned comment added by Lraktsur (talkcontribs) 17:29, 22 July 2008 (UTC)

How to design diaphragm pump flow ? —Preceding unsigned comment added by 58.68.25.90 (talk) 10:51, 15 October 2009 (UTC)

'They can handle sludges and slurries with a good amount of grit and solid content'?

Grit and solid content will block their valves easily, also they are not good self-primers. —Preceding unsigned comment added by Lraktsur (talkcontribs) 17:33, 22 July 2008 (UTC)


I use one to pump waste oil and marbles can pass through it,It rarely clogs and pumps cold waste oil faster the all the other pumps I have tried. —Preceding unsigned comment added by 173.3.175.193 (talk) 01:25, 14 March 2009 (UTC)

The issue here is that there are many different types of diaphragm pumps. They can be used for gaseous, liquid, and even solid media. Most diaphragm pumps are designed for a specific use; so i.e. - using a gaseous diaphragm pump to move liquids can be very problematic, just as using any tool for the wrong purpose would be. This article is extremely poor; among the worst I have seen on Wikipedia. It needs to be cleaned up and represent an overall view of diaphragm pumps in general. The bottom portion seems specific and likely copied and pasted from a company brochure. Rastafl (talk) 19:41, 11 October 2011 (UTC)
