Editing Diaphragm pump (section)

== Characteristics ==
Diaphragm pump characteristics are:
* Self-regulated: The flow rate of an air-powered diaphragm pump can be easily set from zero to maximum just by adjusting the air inlet or the fluid outlet valve. No need to stop running the pump before closing the fluid outlet valve. The pump will just stop by itself and will not consume energy or overheat. Reopening the valve will make the pump restart to resume operation.<ref>https://www.arozone.com/technologies/how-diaphragm-pumps-work</ref>
* Self priming and have good suction lift characteristics.
* Can be designed to handle abrasive [[sludge]]s and [[slurry|slurries]] with a relatively high amount of grit and solid content.<ref name="Verder">{{cite web |url=https://www.verderliquids.com/int/en/pumps-by-principle/diaphragm-pump/how-do-diaphragm-pumps-work/ |title=Advantages Of A Double Diaphragm Pump (Verder Liquids) |access-date=18 September 2022}}</ref><ref>{{Cite web |date=Dec 2006 |title=Tools and Machinery of the Granite Industry, Part III |url=http://findarticles.com/p/articles/mi_qa3983/is_200612/ai_n17196346/pg_4 |url-status=dead |archive-url=https://web.archive.org/web/20080830045951/http://findarticles.com/p/articles/mi_qa3983/is_200612/ai_n17196346/pg_4 |archive-date=August 30, 2008}}</ref>
* Have good dry running characteristics.
* Handle fluids smoothly and carefully, the diaphragm pump design avoids mechanical or chemical damages to the fluid during the transfer: No shear, no foam and no heating.<ref>https://www.arozone.com/diaphragm-pumps</ref>
* Pump design separates pump fluids from potentially sensitive internal pump parts.<ref>{{Cite news|url=https://www.sprayersupplies.com/sprayer-pump-guide|title=Sprayer Pump Types, Costs, and Specifications|date=2018-10-13|work=Sprayer Supplies|access-date=2018-11-21|language=en-US}}</ref>
* A multitude of different diaphragm [[Elastomer|elastomers]] can be selected, allowing compatibility with very corrosive solutions.<ref name="Verder" />
* Can handle low to medium viscous liquids.<ref name="Verder" /> A viscosity correction chart can be used as a tool to help prevent under-sizing AOD pumps.
* Can be effectively driven by compressed air or by electricity. Air driven versions typically achieve the safety requirements to operate in flammable or explosive atmospheres.
* Hydraulically driven versions are suitable for discharge pressure up to 1,200 [[Bar (unit)|bar]].
* Internal pump parts can be suspended and isolated within oil, to promote pump longevity.
* Can be up to 97% efficient.
