Hobby sized peristaltic pumps?

jefm

I was browsing around this board months ago and someone posted up a very cool looking quad-set of peristaltic pumps. However I didn't bookmark it and can't find them again-anyone have a good source on these? I've looked at eBay and such and all I can seem to find are very large, expensive medical type things. What I'm doing does not need precision or speed, I just need a BASIC stamp to keep an evaporation tank full.

Whatever the thing was that was posted looked like four peristaltic pumps in one little block. if anyone has a lead on this or similar I'd appreciate any help! Thanks!

Yeah, that's the unit! Too bad it was a custom build...

Custom build your own. The basic design and construction is simple. A piece of plastic pipe, 2 spring loaded wheels mounted on a bracket, and a gear motor attached to the bracket.

Another option would be a windshield wiper pump from an automotive supplier or wreckers.

Thanks for the replies kwinn :}
The washer pumps is a cool idea, it'd be neat to try to build some, just, not today :} (it's 2C in my garage)

I understand and sympathize. Even lower in my garage.

Note to self: (and everyone looking for a somewhat cheap, simple piston pump)

If I get some of these I'll review them here.
