wouldn't the filter drier stop the oil from entering the pump?
I assumed it would, however some did make it past the filter evident by a small amount of oil inside the intake pump fitting.

is your pump leaking or no longer functioning?
I'm running a 3x36 column with a 12x6 collection pot.
I would say that size pot is way to small for that size column.[/
I thought that might be part of my problem, would adding another spool (4x6) to the bottom of the collection pot solve the problem?

I used to use a 6x6 under a 6x12 and that still was still really close. Ended up doing half floods and half dumps to keep liquid levels manageable.

Sorry ment 6x6. Ok, thanks I'll try that.

A 3 X 36" column puts 8.6" of liquid in a 6 X 12" spool, and 3.4" is too close to the pump inlet, especially with the surge you get when you dump
So adding a 6x6 spool should help?
I would recommend a larger diameter lower spool, not a deeper one.
And reading the last page or so of this thread seems like the only possible issue I can think of.
Would this rebuild include the whole compressor head? Or am I replaceinf seals only? It stopped sounding smooth for a couple runs and I couldn't figure out why...
You need to throttle your valves when you open them for each cycle, you are spattering oil laden butane all over inside your collection pot, or overfilling your collection pot.
It is my understanding the TR21 is also not really designed to operate without a separate heat exchanger, the hot vapor coming out of your TR21 needs to be cooled down somehow so that burden is left on your tank.
My 12 month old appion with only 1 rebuild is still chuggin along. No leaks, the gear box is starting to get loud, ill probably replace that soon.
Once you get to -10 and you go to open the vent valve, I relate it to feathering a clutch. You ever sat at a red light on a hill and instead of the brake, you use the clutch and throttle to keep yourself from rolling back? It works for me, maybe not you, I don't know just my .02 and I have never once had a drop of oil on the underside of my lid.
Like finding that friction point, you have to find that point where the pressure in the collection pot starts to increase, then back it off very slightly and just feather the pressure in. Once it stabilizes, for me that's around 10-12 psi, I slowly open it all the way. Then I move over to the dump valve and do the same thing, this usually brings the pressure up to around 15 psi. You just have to get a feel for it.
Would you be willing to go over my set up with me and help me figure out how to do this? Or any one really???
I don't have a ball valve at the bottom of my materia tube...(can't afford one atm :/ ) But I do have one leading into the tube from the solvent tank, and coming off he the collection vessel to the pump, I should still be able to throttle the flow of tane I beleive but who knows someone's help would be awesome!
I've never seen or had any oil in the collection lid, so splattering doesn't seem likelybut overflowing is possible, tho to be honest I don't know how likely, I run a pretty warm bath, 90-110... So it should be boiling off rather quickly... That isn't to say there hasn't been maybe one or two instances my bath was cold or something,
I've never had the tane back up into the sight glass either, it flows through and its gone... And I'm using Alotttt of tane... Like 6-9 lbs
