Pfeiffer Vacuum’s HiPace 700H turbopumps are high-compression models. With a compression ratio of ≥ 2·107 for hydrogen, they are suitable for generating high and ultra high vacuum.
Due to their advanced rotor designs, HiPace 700H turbo-pumps have a high critical backing pressure capability of 22 hPa. This allows the pumps to reach ultra high vacuum, even when operating with high backing pressures.
