Thank you for the reply. So after speaking with ETS for a system our size they recommended something along the lines of 40gpm+ flow rate and 5kw+ power, so it looks like we will be going with Viking.

I’ve been running this durostar dstp15-ac for over a month now. DI/ethanol slurry in a chopped hot water tank from the scrap heap. Circulates to a 200lb jacketed tank and takes about 30 minutes to get down. I have a basic mesh hose filter hooked on the pump inlet line. Thing works like a champ for 150-200$.

How far away is your 200 lb jacketed tank? Im in the process of trying to do somthing similar. I want to find somthing safe that will get the job done but doesn’t cost a small fortune. Are you able to get the jacketed tank down to -30 -40?
The pump is still working great processing 100lbs/wk. Gets to -40 in under an hour but can chew through 100lbs+ of ice if you run it all work shift. Throw in a 5-10lb mesh bag of 3A mol sieve balls to keep the ethanol-water goo down. My tank is on the other side of that wall, 5ft ish.

Oops lol
We have a pump for sale.
Talk about muff.
But seriously, who spec’d that muffler, never seeen such a large one on a 1” AODD pump before.

I think it may be way over kill for my needs. I only have a 200 lb jacketed tank im trying to chill. Prob gonna build some type of 1/2" stainless coil and pipe it into a custom box thats insulated. 18 gallons per min seems to be alot. Ill look into a little and shoot you a PM. Thanks for the offer 
you wanna fix that link for us?

Is that pump still working great?
Would that pump go well for long hour usage everyday to chill tanks and heat exchangers from a dry ice slurry? If it can handle those temps, and having no priming issues, I’m thinking it should be able to continuously run at cold temps to replace a chiller for recovery.
I wouldn’t recommend it for just about anything unless you know you will never need to prime it. It’s a pain in the ass to prime. I would maybe use it at the bottom of a reservoir but doesn’t have much pumping strength.

Thanks for the update. The priming part wouldn’t effect me, but the actual flow rate would.
I have a brand new MVP liquid pump rated -40c ETL UL etc.
shoot me a dm I’ll do a nice rate. Collecting dust.
That setup worked great 12 hours/day for 3 months. Was still going hard until I bought a busted dslb 50/80 and fixed the broken relay. No need to prime. I did start having flow issues once from water buildup in the slurry bath. I just redistilled the ethanol and everything was fine. The bath setup was chewing through about 1000lbs of ice a week. Lots of ice but capable of getting my two 6"x48" tubes to -60C to -65C.

The flow rate was definitely slower than I wanted. Took about an hour to get a 100lb stainless tank chilled.
