Vacuum components - the connection in your vacuum system
Flange components create the connections for individual vacuum components and are required for every vacuum system. In doing so, the vacuum technology places high demands on the materials used as well as on the manufacture of the components. Pfeiffer Vacuum offers you several proven flange systems which correspond to the different connection standards: small flanges (ISO-KF) in sizes DN 10 to DN 50, clamping flanges (ISO-K) in sizes DN 63 to DN 630, CF flanges (CF) in sizes DN 16 to DN 350 as well as Bolt flanges (COF) in sizes DN 400 to DN 800. In addition to a large selection of standard vacuum components, our product range also includes individual solutions - perfectly matched to your vacuum-related tasks.

Vacuum components must live up to high standards
All Pfeiffer Vacuum vacuum components meet the high quality standards that are placed on vacuum components. The vacuum components are helium leak-tested and show leakage rates better than 10-10 Pa · m3/s for ISO-KF, ISO-K/ISO-F flanges and 10-11 Pa · m3/s for CF and COF flanges. All Pfeiffer Vacuum flange components are welded from the inside for an ideal vacuum. If the geometry does not permit this process, the flange is completely welded through to prevent any leaks such as gaps and blind holes. Suitable materials, clean surfaces and special cleaning methods with industrial machines guarantee low desorption rates. Welded components are finely sandblasted with glass beads or pickled. Alternative surface treatments such as surface grinding, electro-polishing or annealing are available upon request.

Pfeiffer Vacuum offers more than the standard solution
In addition to an extensive number of standard flange and pipe components, sealing and fastening elements, Pfeiffer Vacuum also offers flexible vacuum hoses, elastic connections and sightglasses in all flange series.
