You can modify the 59025 to function the same if I'm not mistaken. Order away plades
The Haskel wouldn't care how many units were hooked to it, it would just continue to remove what vapors were available to it through the plumbing.
Even with well balanced plumbing, , the multiple units would not stay at the same state of completion, because their contents will be different, so while it would work OK for removing the gross solvent, it would average out and compromise the finishes on the multiple chambers.
As a consideration, the Mk VI design uses dual Haskels, with both doing gross recovery, or one doing gross recovery and the other finishing off one of the four pots.
Even though the Haskel will pull a deeper vacuum, it is still running dry under vacuum, which increases wear on the piston seals. I will leave the question open for Dave as to what those effects are on the Haskel design.

I want a ext420 in any trim asap pneumatic electric or battery assist. Please Dave let me know what my time frame is on getting one ready for sale or testing.
What kind of run times are you getting on those tr21's.
Does the ext420 actually have a faster recovery rate compared to the modified 59025. My understanding is it essentially the 50925 with ptfe seals and no need to modify pistons for faster recovery.....Dave am I wrong in thinking this?
While I can appreciate your spit balling, it's seems like your complicating things unnecessarily. I'll be plumbing up the 59025 first week of the new year. Maybe then we can discuss actual operations times, problems and ideas.
I need a pump ASAP what do I do
Dave, do you know what one will pull down to on the bench, dead headed with a gauge?
Hi Dave Is there an email to contact you with?
Gray Wolf, if we've done any testing like that, I'm not familiar with it and the factory is closed right now, so there isn't anyone I can check with. I do know that it will depend on the outlet pressure, that is, if you are only pumping the gas to 50 psig, you will be able to pull to a lower pressure than if you are pumping to 150 psig.
I'll be very interested to hear how low you can go.
Dave
is there any chance someone could conduct tests there, just in case I continue to stumble?
