You will find the latest catalogue on high vacuum from Leybold here

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.

Turbumolecular pumps	Cryogenic pumps	Diffusion pumps
Achievable pump speed: 20 up to 4000 l / s Clean vacuum Small footprint Different mounting positions are possible Low energy consumption	Very high pump speeds that can be achieved (up to ~ 60,000 l / s) Extremely low pressure level Particularly suitable for light gasses Very clean vacuum Only suitable for relatively small gas flows	Very high pump speeds that can be achieved (up to ~ 60,000 l / s) Particularly suitable for light gases No moving parts: robust, reliable, easy to maintain Can only be operated in vertical mounting position Requires additional parts installed to retain the working fluid High energy consumption due to heating of liquid Long time required to preheat and cool
