I've not had a need to spend much time in here folks, so I am asking for some leniency here if you will. Not here to argue brands, just flatten my learning curve.
I've been working with chemical injection pumps a long time and have primarily used diaphragm pumps of some type, usually LMI, but all the major brands. Most often, we use them because we are injecting into pressured systems, but sometimes, it's just out of familiarity. We use them for everything you can imagine, including acid and bleach, but I've never used a Stenner. I remember seeing them in small open systems pumping bleach in my early days, but haven't encountered them since. Excepting here, and a couple of reference pools I've been to see.
I would guess they are less susceptible to off-gassing since they don't compress the liquid, or is it as much a cost/ease of use issue? Nothing LMI is inexpensive, so I would understand if that was in play.
They seem to be the preferred choice here, so I'm just curious why. I'm looking into this more before I build so any feedback is welcome and appreciated.
