I was looking at that pump as well, but ended up going with the CPS TR600 2 weeks ago. It broke after 2 runs and I'm already on my second one :/ My previous pump was the Robinair RG6 and it worked well and lasted almost a full year before any problems. It's pretty inexpensive too , $600 off Amazon with a 1 year warranty.

why are you staying away from appion? any specific reason? i gone through 3 cm-ep pumps those were junk! worst pump ever they kept leaking oil into my product and other various problems. i can say there customer service was excelent. they sent me 2 new pumps for free after mine kept breaking.
also burned through 3 CPS tr-21 pumps. i had to replace the pistons every few times i used them but besides that they were great and fast. i had a T hooked up to my collection pot and had 2 going at a time. we figured we recovered 1 LB every 5 mins
im thinking ill go back to an appion. my buddy has had one for 2 years with no issues.

why has no one tried the inficon vortex? it looks like a good pump and it says any class 3,4 or 5 gas. does anyone know what class r-600 is? i emailed them to ask about it so well see what they come back with
I believe the inficon vortex is a relatively new pump if I'm not mistaken. Perhaps that is why nobody is talking about it . Its got a 1 hp motor in it and is fairly inexpensive . I say give it a shot and report back on its performance and overall gusto!
Did you ever try the trs600? I have a graveyard of broken pumps... what is the best solution!!
WolfWurx, Inc standardized on the Haskel EXT-420 pneumatic, protected by our own cyclonic filter/drier design. Using it, inconjunction with a Vaccon vortex high vacuum pump, we met NEMA 7, Class I, Div I electrical certification requirements and it is as close to bullet proof a pump as you will find, if you feed it clean air, don't run it harder than 50 psi inlet air pressure, or faster than one cycle per second. You also have to periodically lubricate the air shuttle valve.
None of the pumps tolerate shots of gooey liquid well, hence the cyclonic pre-filter.
Based on the condition of the shuttle valve seat when Dave from Haskel rebuilt it, we had one customer over pressure and over speed it, which does beat and eventually deform the shuttle valve seat, and have had multiple reports of a pump being saved by the cyclonic drier.
As a bonus, not only does Haskel have the product to beat, but they actually covet our business enough to work with us to develop one specifically for our purpose, allowed Skunk Pharm Research to record and post a complete factory rebuild sequence by their factory rep on Visio, and for their factory representative to provide hands on advice on IC Mag forum.
Not only a strong product, but strong product support in the field, which is worth its weight in gold at times.

I'm gonna keep being this guy buuuut....
No pump..

graveyard of broken recovery pumps?
sorry i have not followed this thread start to end... but are you trying to pump liquid refrigerant or something?
most recovery pumps should last like 1000 hours with moderate care.
Do you have a CM EP, or a CM EP OL?
Please elaborate, I would love to use just heat and cold to move things but I'm not really sure how to cool my solvent take appropriately, I have a small dewar w a dip tube on the way...
Do the Haskell produce a lot of heat compared to a tr21?
not to cut off grey wolf... but anything compressing gasses will produce an appreciable amount of heat.
however the haskel will be expanding alot of compressed air to do the work of compressing the butane or what ever refrigerant. i would think the haskel would run much colder... if not below ambient.
you could always intall an after cooler on the compressor i guess... but i doubt it would ever be necessary.

sorry i thought all they made were the CM EP OL's now. i got the CM EP OL
The oil from the OL comes from leaching from the bearings, and it would typically be slow enough to show up as a wrecked bearing as opposed to contaminated product.
Way less, because of its bigger bore and slow cycle speed! Maybe 60% as hot on average.
You have the heat of compression with both systems, but the pumps themselves get hot and transfer heat. The temperature of both change with flow, because it helps carry away that heat.
The TR-21 runs extremely hot, especially once it starts under vacuum. Hot enough to fry eggs and burn skin.
Sadly no one sells them at the moment. The WolfWurx designs are owned by Pharmgold, whom closed their doors.
Some folks like Norpene are building their own, so I suggest you ask around.
We used just the cyclone filter. I don't love mol sieve as much after working with the mess and dust for awhile.
After being disappointed by the speed of the cmepol I am going to pull the trigger on a haskel, are these pumps compatible w high propane mixes?
