Leybold Turbovac 350i Turbo Pump

This pump is fully working, and was taken from a refurbished Sciex TripleTOF 5600+ mass spectrometer.

TURBOVAC i series has hybrid rotor bearings: the bearing on the fore vacuum side is a ceramic ball bearing lubricated for life and the bearing on the high vacuum side is implemented by way of a non-wearing magnetic bearing.

Typical for all these types of bearings is that they do not require any lubricating oil which under circumstances like standstill of the pump might diffuse back into the vacuum chamber due to the lack of any pumping action.

Since turbomolecular pumps are not capable of compressing directly against atmospheric pressure their operation will always require a sufficiently rated fore vacuum pump, which we also offer. Depending on flow and ultimate pressure requirements we have different fore-vacuum pumps to suit your systems requirements.
