dunno if it helps, but we use Rietschle Thomas pumps and oils.Might be switching to Mobil though…
Riff42,
Those are good pumps you work with. Single stage of similar design like the Busch RA series. Wha tAndre Cocguyt once told me he recommends because they are durable but also very easy to rebuild. I’ve got a two stage direct drive 8cfm Alcatel that pumps to 10 micron. It is a great pump but I was just curious as to possibly getting cheaper oil pricing. I know that Mobil Vacuum Pump oil comes in quart sizes but I don’t know where to get it locally. And I know that the oil does determine ultimate vacuum.
