I have a system in which I'll need to treat domestic water for iron and possibly bacteria, but i don't want to treat the irrigation water. I was looking into flow control switches rather than powering a pump off the pressure switch when i found the Chemilizer, a water-powered motor and injector. It seems to be used in greenhouses and livestock operations for the most part, but it's accepted for chemical injection for potable water for humans.
Calibration on the HN55 model, which is good for flow rates to 12 gpm, is done by the solution proportions, not by the machine, which is ordered pre-calibrated at a selection of specified settings. The solution never meets the motor, never touches the diaphragm. (For 12 gpm and up, user-set calibration is achievable.)
Several sites, mostly greenhouse and ag suppliers, have the Chemilizer for about $200.
Take a look:

The advantage over a solution feeder like a Stenner is obviously price: the whole Chemigizmo is just a bit more $$$ than a flow switch would have been. The advantage over the pellet chlorinator Gary sells (sorry, Gary!) is that it uses readily available bleach, and the pellets don't need to be rattled down in the feeder so they erode properly.
I did a search of this site in hopes of avoiding being a newb turning over old, soggy ground, but found no mention of this pump here, so i thought you old hands might be intrigued. Anyway, aside from mixing solution, can anyone find a good reason to trash this puppy? Too good to be true?
