https://stream.echo6.co/videos/watch/46990fd1-1f6d-4551-9dfc-7d58960efc78 After taking apart a full automatic foam soap dispenser, I went online and hunted for a foam pump on its own. These pumps simultaneously pump soapy liquid and air together to create a continuous foam-soap on demand. I found just one listing on eBay with the pumps:- https://www.ebay.com/itm/264812164691 The total with shipping is currently $4.54. Lets see if he puts the price up. The construction is very typical for these. A three diaphragm pump with direct motor drive swash-plate style, and matching round rubber umbrella flap valves to make sure the air and liquid end up going through multiple meshes to whip it up into a mousse. The liquid I was using was a mixture of washing up liquid (dish soap) and water. About 1 part soap to 4 parts water. If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
