Yeah, it's odd.

I want to soak a large item (6', at least) in bleach, and really don't want to buy multiple gallons of bleach.    So I thought, what if I bathed it in bleach instead?  It should cut down on waste considerably.

The problem is how corrosive bleach is.   I'm not sure how to find an inexpensive pump that  won't be destroyed by the bleach.  

I don't need a bunch of volume, nor do I need uch pressure.   Just want to keep the item wet.  I don't even need the the whole item wet at the same time.



So does anyone know of an inexpensive pump that runs on household current for continuous duty and won't get destroyed by  sodium hypochlorite?

An AG sprayer pump would probably survive it. Most of them are 12 volts though. Power supplies are pretty cheap though.

For that fact, a cheap fountain pump would probably survive it as well. They are dirt cheap and run on 120v.

They have garden pump sprayers specifically designed to spray corosive chemicals including bleach.  Check your favorite home store or large tool/garden/chem supplier like Grainger

Hand pump sprayer like above and a cheap kiddie pool.

In reply to Justjim75 :

That was my first thought but he stated continuous duty, suggesting he wants it to run for hours.

Oops

Edit: surely we can figure out how to presurize it with a compressor!

Most cheaper pumps are plastic.  I am pretty sure bleach doesn't affect plastic right, it comes in a plastic container.

And fountain pumps are magnetic drive and completely sealed from water. They should last forever.

Ahh.  That is the info I was looking for.   Was looking at ultra cheap fountain pumps, but didn't know how they were built.   Bleach will destroy certain seals, as well as some metals, and cheap pumps don't usually list what they are made of.

Thanks!

Why don't you just wrap her in chain and dump her in a lake like everyone else?

I have an old water softener with a bleach system taking up space in my shed.  It has some kind of pump on it.  I'll see if I can get a model number for you.  Heck, you can have it, but - I have no idea if it works!

Fish filters use a magnetically driven propeller that has mostly plastic parts that come in contact with the fluid they are pumping. They are cheap and can be run without the filter cartridge in place.  Bonus is that it can hang on the side of your container.
