Anyone know of a larger turbo molecular vacuum pump than the Varian V 6000?
Thanks

Planning on doing that, but I'm needing somewhere in the neighborhood of 70,000 l/s pumping speed for He. This will take a number of the Varian pumps. Since I can't use a diffusion pump, due to possibility of backstreaming, I'm stuck with turbos.

We've had our problems with backstreaming of oil in the past, it usually happens when the backing pumps are turned off and the system is left under vacuum. The oil vapor will move upstream and condense in cooler places. We have a series of roots blower backed by two stokes 412s with about 40 feet of vertical pipe that has been painted on the inside. I've had the blowers apart and never seen any oil in them. When we shut down the system an automatic purge valve opens to break the vacuum and prevent the backstreaming. I have a similar system but the oil I had in the blowers came from the blower case when the seals failed in the blower. I just need some big big turbo pumps.
