The search for a proper recovery pump..

Noise and space?

Not much of a downside.

If it is safe, that is what matters. Anyone try active noise cancellation. That was around in 1990's. Would think it is much better, and cheaper now?

RB was pushing the reftec but something changed his mind. I've heard good things about the tr21

I hope the author does not mind. If source wants to be identified, will edit post. It was made by top .01 percent experts (in my opinion).

4) Any company who sells you a recovery pump, that isn’t a Haskel pneumatic, and claims its safe for butane. Appion openly admits that their pumps are downright dangerous to use.
I currently use a CPS TR21 that isn’t rated for but, is designed to recover flammable refrigerants because it has a sealed main bearing and no vapor condenser. I have used it since December 13′ without replacement or issue and it will smoke an Appion or Promax any day.
Please inspect your equipment and remove any dangerous components! We don’t need Closed loopers to start falling in with the BHOtards as a danger to our neighborhoods. We generally have a lot more gas around as well; so the intensity of a closed loop explosion could potentially be much worse. It would only take one to start a campaign against us and throw us in with the open blasters.


BE SAFE!!!!!!

Is there any downside to Haskell, except the price???

A bit noisy without further noise attenuation. Blap, blap, blap...............

The barrier for home folks is that the Haskel uses 40 scfm of clean dry air at maximum capacity, which requires about a 10 horsepower screw compressor, with refrigerative drier and receiver.

10 Hp is on the raw edge of what is available with a 240V single phase motor, with most compressors in that size range offered in 240/480V three phase.

Here is an Eaton E Bay link for a three phase, but they also offer it in single phase:

We've wrecked them all, but I personally have had good luck with them all, excepting for frying the first set of Appion seals trying to recover every last drop of butane when I first developed the process.

I put an upper end kit in it, changed the process, and it provided good service to our cancer program for six months to a year, before requiring another kit.

None of them tolerate liquid butane with cannabis oil in it, nor do any of them like running under vacuum for long periods. It overheats and prematurely wears the seals.

The TR-21 does have a fully enclosed motor, so its winding sparks are less vulnerable, but doesn't have NEMA 7 electrical, so isn't rated for NEMA 7, Division II use, which says that normally there is no immediate hazard, but there can be in a malfunction.

just an idea

just an idea

Whats up guys, after reading through this thread and seeing the direction that everyone is going with this... Would there be anyway to retrofit the triclamp equipment we use into a pump? Spools are like cylinders, and im almost certain that pistons and connecting rods wouldnt be out of reach for a good fabricator. Just spitballin here, but for the price of some of the industrial units mentioned earlier in the thread we could probably develope a triclamp pump hack... probably not the first ime its been thought of, but would certainly be awesome if it worked!

Also, would like to know if anybody has had experience with a Bacharach 3700? 1HP oilless compressor and rated for BOTH tane and pane...looks promising!

Why not try to run the Appion off of compressed air instead of the electric motor since everyone has one already.

Terpp says he has found "THE PUMP" rated for r600, but wont disclose anything yet...

Subzero has replacement gasket set for the Appion, that makes it safe or safer for butane. $200 shipped, haven't bought one yet...

Anyone notice NOT one person has or knows of anyone that has has a problem with the Appion in regards to fire or explosion?

Today I feel like im a carrot...:tiphat:

Is this some secret? I thought we discussed these Chinese pumps already in a different thread. Its a pump from the same manufacturer as this one:
Nanjing Wonfulay Precision Machinery Co., Ltd.

http://cm-green.en.alibaba.com/prod...rant_recovery_machine_can_recovery_R600_.html

I don't get it, seriously, what is with all the damn secrecy in this game?

They are still testing it. If I just discovered something just as potentially game changing I sure as hell wouldn't immediately broadcast it to the community. The fact that we have guinea pigs to move this industry forward makes me happy enough.

My point is these Chinese pumps were already discussed previously and now its being touted as some secret discovery, anyone could have bought one and tested it already.

If you want to be a guinea pig thats fine, but don't pretend you discovered something thats already being manufactured and post secret spy photos of your magic pump that anyone can buy.

Well the status of those pumps isn't really a known fact. Nor can we be 100% certain that they have said pump.

Besides the manufacturer being written on the side of the pump in his photo...

Look back a couple pages in this thread, someone posted a link to a similar pump and I posted a link as well. All of these Chinese companies copy each others stuff anyways, they are practically all on the same street so even if its not labeled the same or by the same manufacturer, there is a 99% chance it is the same internals.
