I love these pumps. You can find em for around $500 that pull to single micron. I use one to pull vac on my closed loop.

I appreciate the feedback and by the sound of it, maybe I was making a bigger deal of it than I should have. I just wanted to make sure before i cracked her open

I have to thank vacuum dynamics for the Alcatel idea. He’s always saying how good they are. Found some deceit ones on eBay for $280 each shipped and not really thinking offered the guy $750 for 3 and he accepted. All 3 run perfect but one has a crack plastic shrod, and now I’m reminded of all the stupid money I spent on across international vacuum pumps.
I’m sure there are other really good cheap vacuum pumps that were ignoring out there.

I know someone in So Cal that sells these used and also rebuilds these for a price much lower than stated up earlier on in this thread. If you want his info shoot me a PM.

Purchased the Alcatel off ebay like others. Ive started Cleaning and Flushing it out…
FIRST THING thanks to @Soxhlet For the FLUSH Recommendation… Ill add a few tips.
Run KEROSENE 70/30 Kerosene/oil For HOUR…
open the intake and oil fill plug and drain the pump… Turn on for 10-15 sec…Turn OFF
FLUSH: OPen Drain and pour Kerosene through INTAKE while pump is tipped forward…
Close Drain. REFILL 50/50 Kerosene/oil Run For HOur With INtake Closed.
REpeat FLUSH… AFter 2nd Flush you should see a noticable difference in the spent oil…
Pretty Happy to see all the black Sludge out of the machine This defenitly Works…
And I thought Tranny oil would smell Make sure you do this outside Burning Kerosene REEKS!

So, I wanted to get 2 of these but only had cash for one. I don’t know how the quality is, but I wanted to share this with you fine folk.

I tried the kerosene, but it went from 50 micron to 400 micron. Running the ballast now, gonna flush it with flushing fluid after that. Might need a rebuild.
You’re supposed to drain it afterwards

I have one of these same pumps needs rebuild also worked great for 3 runs down under 10 micron but after a 2 liter run I got distracted and didn’t shut it down and accidentally vented it to atmosphere and turned it into a oily paper weight
I’ve rebuild Welch pumps with success but these are a slightly different bird
What do you mean vented to atmosphere?
usually after a run I shut my pump down then vent atmosphere to break vacuum but I did that reverse with the pump running at full vac and it went snap then went L.R.A

I did drain it, this was with fresh oil. But u flushed again with flushing fluid and put oil in and it pulled 13.6 micron on the empty system. Still have work to do on it, but I’m happy with the result so far. Using it this run, so we’ll see what happens.

Thanks, I turn off my pumps before breaking vac, but I’ll be extra careful with this one.
It’s running at 51 micron, just hit mains 10 minutes ago.
Edit: 35 micron now
Got it down to 17.8 for a second, but it leveled out at 20 micron. That’s what the vacuum take off allows for since you can remove most of the volatiles from the system.

Aaaaaall riiiiiiight! I can now triple attest to @Soxhlet flushing technique. I’m using flushing fluid, but I did do the kerosene thing aswell. I just pulled 1 micron on my pump. So fucking happy right now.

How hard was the rebuild? I have a 3 week down time, and my trivac has been giving me the stink eye, and is asking for a rebuild.
Lol
