High vacuum pumps operate in low pressure areas, usually below 1 × 10-3 mbar. Depending on the operating conditions (the quality of the seal and the surface, the materials used, etc.), pressures below 1 × 10-9 mbar are typically achieved.

We offer you the right high vacuum pumps for a variety of applications. The product portfolio includes turbomolecular pumps, cryogenic pumps and diffusion pumps.
