Industry proven double stage rotary vane pumps with a performance driven and low noise design

Leybold TRIVAC B oil sealed double stage vane pumps are well known and being used in all areas of vacuum engineering and are equally suited for both industrial production and research applications. The TRIVAC B pumps, used to generate a rough and medium vacuum or as backing pumps in pump combinations with Roots vacuum pumps or high vacuum pumps, have the ability of pumping down from the atmosphere.

The TRIVAC B pump excels with a high vacuum performance by delivering a low ultimate pressure and high water vapor tolerance with an integrated gas ballast. With a low noise level and low vibration, TRIVAC B pumps do not add to the noise in your working environment. The well-proven robust design with low thermal losses and air-cooled design makes the TRIVAC B pumps portable and compact. A comprehensive range of accessories and variants are available to offer a complete solution to meet the requirements of your applications.


The TRIVAC B range is available in six different sizes with an ultimate pressure of 10-4 mbar and a pumping speed in the range of 4 m3/h to 65 m3/h:

  • TRIVAC D 4/8 B Series
  • TRIVAC D 16/25 B Series
  • TRIVAC D 40/65 B Series

Two Stage Oil Sealed Rotary Vane Pumps

New customers’ requirements as well as increased environmental requirements gave rise to the further development of the TRIVAC E. Besides standard voltages and frequencies, Leybold offers world motors, which are specially required by OEMs.

Performance Characteristics:

  • High Vacuum: Typically designed to achieve high vacuum levels, making them suitable for applications requiring low absolute pressures.
  • High Pumping Speed: Rotary vane pumps often provide high pumping speeds, allowing for efficient evacuation of large volumes.
  • Oil Sealed: The oil-sealed design helps to improve the ultimate vacuum, reduce wear, and provide quieter operation.
  • Two-Stage: The two-stage configuration enhances the pump's ability to handle both rough and fine vacuum ranges.

Applications:

  • Vacuum Coating: Widely used in vacuum coating processes for depositing thin films onto various substrates.
  • Leak Detection: Employed in leak detection systems to identify leaks in vacuum systems.
  • Vacuum Packaging: Used in vacuum packaging applications to extend the shelf life of products.
  • Scientific Research: Utilized in various scientific research applications, such as mass spectrometry and freeze drying.

Low cost of ownership with sustainable performance

The innovative Leybold SOGEVAC B single-stage oil sealed rotary vane pumps are ideal for modern industrial applications distinguished by low noise levels, high pumping speeds and high reliability. SOGEVAC B pumps have a pumping capacity range from 10 to 750 m3/h @ 50 Hz with an ultimate pressure of ≤ 8 X 10-2 mbar.

The rotor, having three slots in which the vanes slide, is eccentrically installed in a pump cylinder (stator). The vanes separate the interior space into three chambers. The volume of these chambers varies with the rotation of the rotor. The gas sucked into the inlet chamber is compressed and then pushed out through the exhaust valve. The oil injected in the inlet chamber guarantees the air-tightness, lubrication and cooling of the pump. It is dragged off by the compressed gases and roughly separated by gravity when entering in the oil sump. A fine separation is then operated in the exhaust filter, with an oil loss of below 1 ppm which is a benchmark in the industry.

SOGEVAC B pumps are equipped with an anti-suck back valve at the inlet flange avoids oil coming back into the inlet line when the pump is stopped and a gas ballast for pumping condensable vapors.

Pumping of non-condensable gases

SOGEVAC B pumps show high reliability in applications with non-condensable gases when operated without gas ballast. If the composition of the gases to be pumped is not known and if condensation in the pump cannot be ruled out, the pump is operated with open gas ballast.

Pumping of condensable gases and vapors

With the gas ballast open and at operating temperature, the SOGEVAC B oil sealed rotary vane pumps can pump pure water vapor up to the values indicated in the Technical Data.

The necessary oil is supplied in the pump for those bigger than 65 m3/h.
