Vacuum Pump Turbopump with high compression specifically for light gases
With the new HiPace 300 H, Pfeiffer Vacuum presents the most powerful compression turbopump currently available in the pumping speed class of 300 l/s. With a compression ratio of 107 for hydrogen, it is suitable for generating high and ultra-high vacuum.
Due to the high compression ratio, a low residual gas spectrum is created in the chamber, which is desirable for mass spectrometry applications, for example.
Thanks to the advanced rotor designs, the HiPace 300 H has a very high critical backing pressure of 30 hPa. This allows the pump to reach ultra-high vacuum, even when operating with high backing pressures, as occurs in combination with diaphragm pumps. Due to the integrated “intermittent operation” function, the HiPace 300 H switches on a connecting backing pump only if the backing pressure is no longer adequate. This reduces the energy consumption of the entire vacuum system by up to 90 percent.
The HiPace 300 H has a so-called hybrid bearing. This combination of a ceramic ball bearing on the fore-vacuum side and a permanent-magnet radial bearing on the high vacuum side creates a particularly robust bearing concept. This in turn leads to very high reliability and a long service life.
