2.8.3.1 Mechanical-bearing turbopumps
In the case of HiPace turbopumps with oil-lubricated ball bearings on the backing-vacuum side and permanent magnet-bearings on the high vacuum side, a distinction is made between the following turbopump series:
- HiPace turbo drag pumps with Holweck stages offering pumping speeds of less than 1,000 l / s with ISO-K flanges to generate high vacuum for standard applications, or
- with bakeable CF flanges to generate ultra high vacuum
- Classical HiPace turbopumps offering pumping speeds of over 1,000 l / s with ISO-K flanges to generate high vacuum for standard applications, or with bakeable CF flanges to generate ultra high vacuum
- Classical HiPace-C turbopumps with coating and sealing gas system for corrosive gas applications
Classical HiPace-C turbopumps offering pumping speeds of less than 1,000 l / s but with coating and sealing gas system for corrosive gas applications are available upon request.

Standard HiPace™ turbopumps
The advantages and disadvantages of classical turbopumps and turbo drag pumps are shown in the table 2.14.
