Two-Part Dosing Pump Comparisons

[Maeda]

I know litermeter is king, but i'm also looking for the other economical options out there. There seems to be a serious lack of information regarding peoples actual experiences using dosing pumps.

If anybody has had them i'd like a little review if possible as I can't seem to find information pasted around.

Aquamedic?

Sentry Pumps?

Twopartsolution dual head?

Other?

You can always pick up a laboratory peristaltic pump on the bay. They generally have several slots to run multiple tubing at the same time, at the same rate. I bought a Brinkman for 25 bucks. That thing is built like a tank. I use it to dose my two part. It does not have an lcd readout and rate is set by a regular potentiometer so it requires a little work to get it set. I replaced the potentiometer with a fixed resistor so that it pumps 20 ml per hour from each container (1 gallon per week of each part) and it runs like clockwork. So, it depends what you want to spend. But if you look around, and willing to maybe have to do a little work to get things set-up, you can get reliable dosing on the cheap. And I'd bet that nothing on the market is built any better, if even nearly as well, as this pump.

I have a Cole Parmer dual channel. It's a champ, been running 24/7 for a couple years now with no issues. They're pricey though, if you find one used swoop on it!
