Robust and reliable

The robust design and the proven pump technology ensure a long service life and reliable performance. The efficient oil supply supports the lubrication, sealing and heat dissipation of the moving components and contributes to safe continuous operation.

Versatile and service-friendly

The TRIVAC series is suitable for numerous industrial, scientific and laboratory applications. Depending on the version, functions such as gas ballast, various seal variants and different connection configurations are available, allowing the pumps to be adapted flexibly to different process conditions.

Operating principle

The Leybold TRIVAC B series works on the proven principle of two-stage, oil-sealed rotary vane vacuum technology. An eccentrically mounted rotor with vanes rotates inside the pump housing, creating continuously changing working chambers. The air drawn in is compressed in the individual pump stages and is then expelled through the outlet.

The pump oil performs important functions for lubrication, sealing and heat dissipation and enables reliable and efficient vacuum generation. Thanks to its two-stage design, the TRIVAC B achieves a high ultimate vacuum and is suitable for demanding medium vacuum applications.

The robust design, reliable operation and long service life make the TRIVAC B a versatile vacuum pump for industry, research and laboratory applications. Depending on the version, functions such as gas ballast and various seal variants are also available to adapt the pump to different process conditions.
