Two-stage Rotary Vane Pumps - Pfeiffer Vacuum

Two-stage Rotary Vane Pumps

Standard pumps with mineral oil filling cover a broad range of uses in practically all fields of vacuum technology.
Rotary vane pumps in the instrumentation series were developed for sophisticated applications in analytics and industry. Due to pressure oil lubrication, they can also be operated with high gas throughputs. The typical sound pressure level of these pumps is only 49 dB(A).
In contrast to the standard pump, these products have a frictionless magnetic coupling. Oil leakage from a wear-prone conventional shaft seal is ruled out in these models

Corrosive version with mineral oil

These corrosive versions of our rotary vane pumps are designed to be operated with mineral oil. These are used in sophisticated applications with corrosive gases. The costs of operating fluid remain relatively low due to the use of mineral oil.

Corrosive version (PFPE)

These corrosive versions of our rotary vane pumps are prepared for operation with Pfeiffer Vacuum perfluoropolyether (PFPE) operating fluids. Due to the inert operating fluid, these pumps can be used in highly corrosive processes. PFPE operating fluids must be ordered separately.

Magnetically coupled corrosive version (PFPE)

These corrosive versions of our rotary vane pumps are prepared for operation with Pfeiffer Vacuum perfluoropolyether (PFPE) operating fluids. Due to the inert operating fluid, these pumps can be used in highly corrosive processes. By using the magnetic coupling, the integral leak rate of these pumps is less than 1 · 10-7 Pa m3/s. This maximizes the operating reliability in corrosive applications. PFPE operating fluids must be ordered separately.

With its DuoLine and Pascal two-stage rotary vane pumps, Pfeiffer Vacuum has offered two very successful ranges for many years now. Their long life and pumping speed, irrespective of the gas used, are the outstanding properties of these pumps. Two-stage rotary vane pumps can be used in the pressure range between 100 hPa and a pressure roughly a decade above the final pressure. Pumps belonging to the DuoLine series cover a pumping speed range of 1.3 to 300 m3/h. In the 5 - 21 m3/h range, Pfeiffer Vacuum also offers the Pascal series as products with superior vacuum performance. Pumps in the Pascal range are principally used as standalone pumps. Both series are available in a standard version with a shaft seal for use in straightforward applications. The Pascal series is additionally available as an instrumentation version for more sophisticated applications, such as frequent cyclical pump-down processes (load locks). There are various corrosive versions available for pumping aggressive media. DuoLine pumps with a magnetic coupling dispense with the need for shaft seal maintenance.
 

Typical applications are found in widely ranging sectors:

  • Analytics (mass spectrometry, electron microscopy)
  • Coating technology (surface protection, decorative films, display units, monitor screens)
  • Medicine/pharmaceutical technology (plasma sterilization, freeze drying)
  • Vacuum metallurgy (vacuum soldering, vacuum sintering, vacuum alloys, furnace construction)
  • Leak detection technology (vacuum systems, automotive tanks, airbag cartridges, packaging)
  • Research institutes (elementary particle physics, fusion research, laser applications)
  • Lighting industry (light bulb manufacture)
