Industrially proven two-stage rotary vane pumps with strong performance and a low-noise design.
Leybold TRIVAC B oil-sealed two-stage vane pumps are well known and used across every field of vacuum engineering, equally suited to industrial production and research applications. Used to create rough and medium vacuum or as backing pumps in combination with Roots vacuum pumps or high-vacuum pumps, TRIVAC B pumps can pump down from atmosphere.
The TRIVAC B stands out for its vacuum performance, delivering a low ultimate pressure and high water vapour tolerance with an integrated gas ballast. With a low noise level and low vibration, TRIVAC B pumps do not add noise to your working environment. A well-proven, robust design with low heat losses and air cooling makes TRIVAC B pumps portable and compact. A comprehensive range of accessories and variants is available to provide a complete solution for the requirements of your applications.
The TRIVAC B range is available in six sizes with an ultimate pressure of 10⁻⁴ mbar and pumping speeds from 4 m³/h to 65 m³/h:
