Hey guys, apologies if this is old news but it gave me a bit of a think last night. I read someone saying that peristaltic pumps were very expensive and I was surprised given how simple the mechanism is. The principle is that by squeezing the pipe and running the liquid along (sort of like squeezing the last toothpaste from the tube), you can pump without making contact with the fluid.
I saw a hire sprayer in my local garden centre on Sunday. On closer inspection it appeared to be based on a simple peristaltic pump.
It consisted of a metal disk, 3 bearings or stainless steel spacers and some flexible pipe fixed to a cart or sack barrow.
The bearings were located in an equilateral triangle on the disc and the pipe was run tightly over the bearings. The pipe ends were fixed to the frame of a cart and the disc was attached to the wheel. Rolling the cart caused the disc to spin and drove the liquid along
It set me thinking that it'd be easy to modify this design to include some beerline attachments and maybe a handcrank made from a couple of bicycle sprockets or even have it directly driven from a hand drill. It might be an option for some of you guys that filter beer. I think I'll bodge one together to remove the need for syphoning.
Sorry if this is a bit confusing or if you all know it already, I needed to get it out of my head.
PS. I think this is my first post, hey everyone!
