Hello again!
The title says it all folks!
I need to pump a iso/dry ice slurry but am having a hard time finding a pump that can handle those types of temp.
peristaltic pumps was what I thought I needed. But the cold will most likely freeze the plastic tubing an cause it to break
I’m running out of ideas and sanity.
Please help!!!
I had a chiller pump go out recently. I replaced it with something like this:

What volumes are you pumping and what vessels are you moving in and out of? A couple years ago I was doing bulk winterization and filtration with bright tanks and lenticular filters and moving 500+ gallons of -80 oleoresin with a used slurry pump that I think came from some jelly/jam factory or something.
Ask for Serge. If your’e not in CA, he’ll ship.
It depends on your scale though and your shop capacity I guess, but it 110% works really well. I changed the seals on them is about all, and they pushed 100+L an hour of the filthiest darkest fattiest vile warm BHO crude I’ve ever touched, through 3, 16" x 4 lenticular filters like it was water for first pass winterization and left less than 1% fats. Don’t call McMaster-Carr though, they hate plants and fire hash.
This looks a lot like my vintage ebay challenge slurry pump for sure.
Hydroponic mag drive pump…
I prefer Danner pumps,
It’s actually pretty neat how good those things work, I have a couple I’ve used in the past, and I’m amazed the plastic can hold up.

Hi Carltonkent, how cold are you going? We may have something for you, I’m write back shortly. Thanks, Greg/Heyes Filters Inc.
Those will seriously handle ISO and EToH allowing with cryo temps and don’t grenade?!?
Interesting…
Many people use them for this. I personally have not, but it’s the route I’ll soon be going once everything is fully jacketed
I’d stay away from Ampco pumps, just finished dealing with an improperly designed pump and it took 6 weeks to get a working replacement.
I think I’d be cracking the pump open and silicone the shit out of it.
Just to be safe
That thread is what directed me to the mag drive pumps actually.
@Dred_pirate is the one who pointed the mag drive pumps out in that thread, just wanting to give credit where it’s due.
@HeisenbergInd, when I used them, they worked great. And the mag drive box is pretty well isolated from the motor.
They’re definitely not certified for this application, but they do work.
Is a pump a requirement ? Would pushing your solution with a noble gas be an option? Maybe something like nitrogen? Certainly be much easier and cheaper if so.
You need the recirculation
Bingo or just an air compressor and pressurize the tank to push it out.
