well i recently upgraded to a jacketed spool (already have a jacketed shatter platter) hoping it would help with recovery times. im honestly shocked at how little that helped. i cant say i noticed one minute of difference during recovery.
ive been wanting to set up dual cmep's for a while but just dont have the extra money, then i glanced over and saw my old trs sitting there. for about $1200 i can get all the plumbing to redo my solvent tank and set up everything for dual recovery. and since i already have a working trs21 i figured id save the cash and just use that instead of buying another cmep.
any opinions or things i should know about using these pumps together? thanks

just for clarification each pump will be going into its own port on the collection tank. they will not be run inline

Shouldn't be an issue running them together into separate ports in the collection tanks. We've run dual pumps into the same port and it works.

i figured it wouldnt be an issue but just wanted to double check. thanks as always graywolf

There is one issue that could be a problem for you.

Are you using a CMEP or a CMEP-OL? The CMEP is not an oil less pump?

[gumby420]

cmep ol. sorry i always just shorten it down to cmep

[gumby420]

i got the cmep ol and swapped out the trs21 because i thought it would boost recovery times. no noticable difference at all. but for as much complaining i hear about the cmep ol i can say i have not had one problem with mine. i got it last january and its been running roughly 100 hours a week ever since. with zero problems. but i do wanna have the trs21 hooked up not only for faster recovery but also just as a backup in case one pump goes out, i wont have any down time

I run 3 tr21s and a cmep-ol on a system and plumb them all into a 1/2" condensing coil before the tank. When running crude, we can recover over a pound of butane a minute because we run the water in all of our jackets at 160f. When doing cold runs, recovery is slowed down because we run the jackets at 90f. The hotter the fluid that you pass through your jackets, the faster you will recover.

I can assure you it will fail, however. As soon as the piston seals become even slightly worn, larger amounts of butane will make it into the crankcase and begin pushing bearing grease out through whichever piston seal is worn. This is inevitable with the cmep-ol, just just know what will happen at one point, and it may or may not contaminate your solvent tank depending on how long it's run after that. I strongly vouch for another trs21, but thats also because Ive got nearly three years out of one with no rebuild yet. Couldve got 5 trs21s for what im into my cmep-ol for now. OH, AND ABSOLUTELY DO NOT HAVE BHOGART REBUILD IT FOR YOU!!!! They did a shit job on mine, and for some reason they grease the crankcase up. Took a shit inside after running it one time only! And the pump was ran exactly as told, elevated, with proper filtering, no vacuum ever, and a self draining coil and it didn't matter.

wow thats crazy high. the highest ive ever run the water in the jackets is 95 and thats only for distilling and crude runs. for cold runs i have my recirculator set at 82. next time i run some crude oil ill bump up to 120 and see how it does. i purge super low in my ovens so i dont want my jacket temps higher than my purge temps.
