Model: DS 102 Two-stage Rotary Vane Pump + Oil Mist Eliminator KF 25 949-9395 serie
Thanks to a very simple and highly reliable design, this field proven DS Series rotary vane pump provides excellent vacuum performance. The quality and manufacturing standards ensure that the DS rotary vane pumps provide high pumping stability for light gases, low noise, minimal oil backstreaming, and a long operating life. The pump?s two-stage design allows for low operating temperature, minimal backstreaming at low pressure and good pumping efficiency and gas ballast. It delivers a pumping speed of max. 114 liters per minute, low noise and a long operating life. It conforms to European Union directives (CE) and Restriction of Hazardous Substances (RoHS) requirements, and it is also UL and Canadian Standards Authority (CSA) approved.
Oil Mist Eliminator KF 25 949-9395 serie is assembled at the outlet of the rotary pump and the main purpose is to purify the exhaust gases from oil mists. The use is advised for pumps which have to work for a long time at intake pressures exceeding 10 mbar, or with the ballasting tap open.
Applications:- Analytical Instruments:
Dual Stage Rotary Vane Pumps are practically the only primary vacuum pumps used on GC-MS and MALDI-TOF Instruments:
GC-MS typically uses this small pump - the pump is needed to rough the system and back the high vacuum Turbo or Diffusion pump. MALDI-TOF depending on system size, uses the DS102 as roughing or interface pump.
- Leak Detection:
DS102 is typically used to back the Helium Mass Spectrometer Turbo or Diffusion pump.
- Industrial Vacuum Processes:
Vacuum coatings, Metallurgy Vacuum Furnaces, Lamps and TV Tube manufacture, Sterilizers, Freeze Dryers, Glove Boxes, High Speed Centrifuges, and Flywheels (for energy storage) represent the main Industrial applications for Dual Stage Rotary Vane pump.
- High Energy Physics and Research Laboratories:
In these applications the Rotary Vane pumps are mainly used in combination with Turbo pumps. The combination is typically used to rough and pump High Vacuum experimental chambers or to start Ion Pumps in ultra high vacuum systems.
- Dual Stage Pump:
The two stage design allows low 10-3 mbar operation, low operating temperature, minimal backstreaming at low pressure, good pumping efficiency and gas ballast in the high 10-3 mbar region.
- Forced Oil Circulation:
The dedicated oil circulation gear pump ensures efficient and reliable lubrication of the pump from atmospheric pressure throughout the entire vacuum operating range.
- Built-in Oil Shield:
This feature minimizes the oil mist at the pump exhaust. Apart from drastically reducing the oil consumption over long periods of operation, this results in a reduction of air pollution limiting the impact on the environment.
