Not sure if these questions have been asked here but : Would your tank have to have a dip tube to pull the liquid butane out or would the tank be upside down? Wouldn’t it just be better to keep using nitrogen?
So I’ve been curious about this liquid transfer pump Bhogart makes and has been trying to sell me on as a way to work around using nitrogen to move my solvent and clear my columns. And they’ve offered it to me for a very good price, also with a variable frequency drive, because of a bunch of bullshit we’ve dealt with our order so I’m considering it because of the heavy discount. I’m just not totally understanding it.
I was assuming the pump would go right after injection valve on the solvent tank, and pump the cold solvent into the columns then through our crc and into the collection. But even if it did have enough pressure to move the -40f butane through the columns and crc, then we would still have to clear the columns of the butane still in them. Is there some way to push vapor through this to clear the columns? They’re saying this can completely replace using nitrogen which if was true I’d definitely buy it. So would this work to actually replace n2? MVP Liquid Transfer Pump — BHOGART

You could use the output of a recovery pump or use nitro for the last little push

Those things are for feeding an ffe evaporator that is bound to have a higher pressure than the feed tank has

That’s what my impression was but they’re swearing it will completely replace n2 which I just don’t see how it could

Yes, in order to access liquid, there needs to be a dip tube or valve at the bottom of your tank, flipping the tank upside down works but probably should not be considered an acceptable solution for most.
No, just using nitrogen is not always the correct response. If one wants to circulate liquid, through a heat exchanger or magic dirt, a liquid capable ( and or hash capable) pump is required imo.

I run a liquid transfer pump, its not self priming. I still find i need a head pressure or gravity to feed the damn thing

Luckily my tank has a valve on the bottom @Apothecary36

Jeezus. That’s one of those “oddly satisfying, visually pleasing” kinds of things. I’m just impressed.

Why did you switch to nitro? What didn’t you like about the mvp?
nope will not

cuz the unit doesnt have enough suction so to not have huge yield losses… I need that pressure on top to get the rest of the juice out of the columns…
Its not a bad unit works well…
Just not for my needs.

Ya I’m using it for injection only. Then use n2 to push the butane through my columns and into the collection. I’m loving it. Not having to use n2 to charge my tank is saving time and money. And my tank sits at a partial vac literally the entire time I’m running.

Air-Powered Transfer Pump for Harsh Chemicals, PTFE, 3/8 NPT Side Intake and Side Discharge, 6.7 gpm
Kinda bringing this back from the dead, but has anyone used one of these?
The working temp probably wouldn’t work for most operations. I’m looking to use it as a return to the ole solvent tank from a butane ffe.

I’ve used the aro transfer pump, it needs a head pressure to feed the pump or a gravity feed. It doesn’t leak, but I wouldn’t say that it’s the best choice.
Really? I’ve never used that particular one, but other AODD pumps I’ve ran all self-primed just fine.
