Chlorine diaphram Pumps

[beastud 14]

If someone already posted on this, I apologize ahead of time but I didn't see any matches.

Has anyone tried these pumps for pumping sodium hypochloride or sodium hydroxide (basically chlorine or caustic solutions)? It looks like a reasonably priced alternative to 12V electric pumps or the other more expensive diaphram pumps.

Or this one?

I don't know what you are planning on using the pump for, but 220psi or 360psi is more than you need for roof cleaning or for applying cleaners on wood.

That is true but I think that may be max pressure. I am hoping to regulate that down.

Doesn't look like you can regulate the first pump.

The second pump looks like it can be regulated.

Kind of pricey on both pumps. IMO.

Not much of a "Northern" kind of guy myself, mainly because the only thing the staff knows is how to direct you to the cash register.

However, delevan makes good pumps. Shur-flo makes good pumps.

There is also the bandit setup, which I hear is good.

If you are going to be pushing 5.5 gpm's on all of your projects then you will want a tank setup as well.

Spend a little more and get a package on a skid.

What exactly will you be using this application for?

I want to spray buildings, roofs and decks. I love the input but I am done with 12V pumps. The Fat Boy would be my choice if I went back to 12V.

I want to take things to the next level. If I could get a fire hose to work to spray chems.....I would!
