Schott is just a German brand of borosilicate. Definitely better than China boro (Simax is even better). Quality of craftsmanship is what it really comes down to though.
Schott is pronounced like shot, but commonly referred to as Scott.
I’m assuming you just made a typo though.
The Scott I am referring to is
Scott Duran gmbh wich is owened by Carl Zeiss foundation.
They are the producer of glassware but also off glassware parts the NS couplings in particular are very precise ( the lathe they use is amazing where final polishing and measurements are made ( Carl Zeiss technology)
The chineese lady that sells the spd copy s of summit research usses scoot Duran pieces to manufacture the spd s so some chineese is

*Schott Duran.
Borosilicate was invented in 1887 by German chemist Friedrich Otto Schott. Carl Zeiss and Ernst Abbe were business partners of his.
The Duran name was registered in 1938 (now owned by DWK Life Sciences GmbH).
The Carl Zeiss Foundation owns Schott AG
Anyone can still purchase Schott’s Duran tubing to make their own products, but finished products with the DURAN® label are from DWK Life Sciences now.

So you’re saying for $400 you can get the repair kit for your pump but for $250 you can get a brand new HVAC pump… don’t you think it’s worth $150 to have a much nicer pump that’s completely rebuilt?
But hey you probably have different considerations than I do.

What size boiling flask is he using?
He does explicitly state that “vacuum depth” is the key…which is what everyone here has been telling you.
Are you running high quality glassware? The cheap stuff usually leaks…making more suck an important piece of the puzzle.
You’ve asked professionals for their opinions, you don’t like the answers. Ok, then Ignore them…figuring this out yourself can’t be too hard.

I’ll spend the whole day ruining my peace getting mad with disassembling the pump, then the repair kit may fail somehow, then I’ll have lost another day and another 400€

That poor little pump. Do all of the things people already recommended.
Let’s pretend it works:
I don’t know what this is being attached to, but there is no safe level of solvents for your apartment.
Let’s pretend there is a safe and reasonable home use for this pump:
This pump will exhaust an oil mist that is disgusting and not to be inhaled. It will coat everything, including the inside of your lungs. At the minimum, make sure you are using an oil mist eliminator on the exhaust (this is a part that needs regular maintenance) and exhaust the pump from there out of the building.
Protect your ears
This is probably just a really bad idea.

Good luck with that bud.
But regardless I would take the advice of making sure that you Purge all solvents ahead of running everything inside your house and even then still take the advice that was given you on numerous occasions to make sure that you ventilate the exhaust out and preferably if you can a mist in line before it even ventilates outside.
I wish you luck in your Endeavor and try to stay safe.
I’ve definitely done ethanol extractions in apartments….. ethanol can be done perfectly safe. Butane is a whole other animal.
so what do you have for input material? are you making or buying crude? are you going to be winterizing? recovering solvent?
putting an oil mist into your living space sucks. putting a solvent filled mist into it can be devastating. the correct vacuum pump for distillation (two stage rotary vane) is different from the correct pump for solvent (ethanol) recovery (diaphragm pump).
see perhaps : proper venting of vacuum pumps & Rotary vs centrifugal vs diaphragm pump
dunno. hooking it up to a gauge and a pump is where I’d start.

Simax, DURAN, Kimble, PYREX, ISOLAB are all high quality boro. Different products conform to different standards, but this should be simple to verify. All offer products with DIN/ISO standards.

Imagine being this much of a dismissive tit to professionals offering their experience after years of devoting their own time & money.
Especially when you came here asking for advice.
By all means- stick with YouTube & go back to the air fryer for your chemist cosplay.

I assume your not willing to pay 150€ for a tiny bit of krytox. So I guess your in for the long haul off leak hunting good luck

Bro here are but just a few of my pumps… I feel like a complete and total moron. Could have saved the whole shitload of money all I needed is $150 pump that would make everything else I have obsolete
And what makes it even worse is that Edward 30 is burn spanking new.
Fuck I wish you would have given me the heads up before I got it. And now I just got a bunch of expensive paperweights

Why? For $150 I can replace any pump in that video with the pump he wants to buy. Everything in the video was just a waste of money.
