Cps has a stainless model meaning the guys are stainless as opposed to copper. It's about a g and soon to be on back order.
I agree a hundy with rb on the other pump, and feel the same about cps tr21ss..... Same pig, new lipstick

Not what I am hearing, I am told it's supposed to get a rating for r600. I would like to see info on this.

I think we will start to move away from Recovery pumps and start running compressors for r600a or pneumatic pumps.. Does anyone know of a good compressor for r600? I know they are all over europe. Any european members have a r600a fridge?

If you look at these photos here: http://www.cascadiadynamix.com/photos
Bigfoot extractor is using a stainless compressor? Am I wrong? Look:
And what is this about Subzero making the Haskel two stage? I dont understand but they said they made the two ports go one direction on the Haskell by revering a part. Supposedly made it twice as fast, Ii is on there facebook.
I am going to make a heated expansion column for the cps but I want to also attempt to make it a stainless pump myself and put all ptfe seals in it. I will contact cps and let them know what I am doing and try and get the to give me info on the stainless one instead on monday. I might wait until I blow it, ha.

As it seems they have active conversations going on refrigerant tek forums. http://www.refrigeration-engineer.com/forums/showthread.php?41630-floral-extractor-using-R-134a
I can't speak to what Bigfoot is using, all I can mention is what I see in their pictures, which causes me to not put any interest into what they are doing honestly.
1) that their Bigfoot 150 system in pictures looks like it uses a PSF-12 Stainless bottle from Eagle Container, which they themselves (Eagle) have said is not rated for pressure of any kind.
2) The big tanks in the first picture you posted look very similar to modified 10 Gallon Ball Lock Beer Kegs.
3) I see butterfly valves and exposed tube style sight glasses all over the place.
4) Their larger system uses a 6" column
GW posted about it a few days back after talking with Haskel, you have to rotate one of the heads and change a hose out so both cylinders run in parallel or something of that nature.
Bending stainless tubing without the proper tools (which aren't cheap) isn't easy or fun, trust me.

Hehe, I remember seeing one of these threads back in 2009 with gray wolf popping up and asking questions.

I have all the tools needed.

Obviously you dont know what you are talking about. I work with pressure containers in brewing just like those. When I load my mash I load the tank with nitrogen to force out all air. I do this at 100psi.. There site said they are met for 60 and tested to 3 times that. Thats what Triclamp manufacture rate at as well but we use for much higher. Also, those are not from eagle. "Corny Kegs" can be used and they ARE met to hold pressure.
Which part is incorrect?
1) The part that PSF-12 Eagle Stainless bottles are not rated for pressure? They are not, call Eagle and ask. If they aren't the ones from eagle, what are they? Where are the pressure ratings? ASME pressure vessels typically have crush rings on the bottom.
2) That those tanks dont look like modified 10 gallon ball lock kegs? They sure do. I didn't say anything about them not being rated for pressure. Corny kegs most certainly are rated for pressure, I didn't mention them anywhere in my post. The fact you have to typically bring them up to 30psi to get the damn things to seal in the first place and the stamps on the side of the metal will tell you that much.

I did call them, and they said of course they have pressure rated bottles. And the Corny tanks are what I thought you were talking about. Corny tanks DO seal under 0 psi as I use keep them air tight after cleaning with detergent for brewing.
http://www.eaglestainless.com/bottles.cfm?category=bottles&product=asme According to this they can handle a considerable psi more then glacier claims the tri clamps are met to.

Dude thats not my point. My point is that is not what is in the pictures of the Bigfoot 150.
Those ASME pressure bottles that Eagle sells are thousands of dollars, they wouldn't be able to sell the system for the price they do if they were using those things.
The PSF-12 bottles on the other hand can be had for $99 on ebay. I am not trying to get into an argument, I just don't think we should be taking engineering advice from a company who is selling systems with so many glaring flaws.
Even if they are using pressure rated bottles, the other facts I listed still remain with the unprotected sightglasses and butterfly valves.
How do you know they are sealed if you keep them at 0 psi? I am not being a smart ass, just curious. I would love to pass on the knowledge to all the homebrew guys I know who have trouble keeping their cornies sealed.
This is the type of keg I was talking about that looks like in their pictures:

This is the type of compressor you don't want to see. Not oil-less and have a very real chance of contaminating your entire butane supply with oil. "rated for R-600" doesn't mean it's right for this application. Nice and quiet, but it's still a refrigeration compressor and should not be used in a system that is producing products for human consumption.

According to them the stainless one is oil less, I am interested for sure.

Not saying they use all the right parts and methods but I am very interested in the evaporator. The butane and oil goes into a tank with a internal heater it is then vaporized under a surprisingly low temp and sucked into another container as liquid I believe. Then a oilless liquid compressor packs it as liquid into another tank. Then I believe the smaller tanks are expansion tanks and collection maybe? Can Graywolf explain? It is all top fed obviously but what is with the carbon in the sight glasses? Are these filters or also evaporators?

-Use a little food grade lube on the oring prior to sealing
-Pressurize with 20 – 30 psi initially then back off the pressure
-Twist the lid back and forth under pressure to find the “sweet spot”
-Bring to zero when tight and sealed.
This will leave you with a sealed container after you sanitized that is not under any kind of pressure if you do it right and your Orings/gaskets are clean and good. But this conversation is going down elsewhere and this is off subject.
If you haven't started the progression towards pneumatic recovery you need to. As you have made very apparent you are one of the "largest producers in SOOR" so I highly recommend you stop trying to find or build to proper recovery pump because it already exist.
Get 3 phase, a compressor and a Haskel. Problem solved

I am selling top feeders to my buddies and they need some advice on what pump to buy. soormade.com The site is late but will be up next week. I am going with a Haskel when I am in a OLCC facility as my neighbors will HATE me. I am on agriculture land with close neighbors. I Like the CPS, excited to see what the pump turns into over the next few years. We already have a CP 10 horsepower that only has 20 hours on it.. I need Filter dryers and all the plumbing and of the Haskel.
