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.
