Ebay peristaltic pumps

[gbru316]

I've seen several ebay listings for "12V DC DIY Dosing pump Peristaltic dosing Head For Aquarium Lab Analytical water."

Anyone have any experience with them?

At under $20 apiece, I'm tempted to order 2 of them and build a doser out of an arduino.

Just saw a similar question, but those only work a for a couple months before the tubing burns out. So keep that in mind if you get one.
If you are doing Arduino control, you could power a 6v pump off 5v, the same power going to the Arduino, and reduce wiring.

Is the tubing replaceable? It looks like standard silicone airline tubing.

I think it's a standard tubing, but maybe not airline. Although I don't know how tricky it is to replace the tubing. Probably not too hard, so I guess you could buy one and try it out.

I had bad luck with them. They only lasted several weeks. How did you mount them?

Which pumps are you talking about? EBay doesn't sell anything, they provide a place for other people to sell their stuff. What you get depends on which one of those people you are buying from.

I know ebay doesn't sell anything, but I got warned for posting an ebay link in the past, so I don't want to post one again. The item names are above.

I haven't bought any yet, I'm still trying to decide whether I should or not.

I have the BRS 50 ml/hr pump (they also have a 5 ml/hr). You might find it used somewhere. Tubing is over a year old and runs every day for kalk top off.
