Sogevac 25B

Oil sealed rotary vane vacuum pumps are being used in all areas of vacuum engineering . They are equally suited for both industrial production and research applications .



They may be used to generate a rough and medium vacuum or as backing pumps in pump combinations with Roots vacuum pumps or high vacuum pumps . The SOGEVAC pumps excel also to their low noise levels and smooth operation .

Protection of the Environment
The built-in exhaust filter ensures an oil-mist free exhaust gases over the entire range of operating pressures from atmospheric pressure to ultimate pressure .

Many years of experience in vacuum engineering and the latest developments in pump technology combine in the SOGEVAC range the capability to adapt to the requirements of both the industry and the environment . The comprehensive range (pumping speeds ranging from 10 to 1200 m 3 x h -1 (5 .9 to 707 cfm)) allows every customer to select the right pump for his particular needs .

Quiet Operation
SOGEVAC pumps are designed throughout to keep the noise level as low as possible . This is ensured by optimized running and sliding speeds and the selection of low-noise drive motors, as well as perfected manufacturing techniques using CNC automatic machines for optimized tolerances and reproducibility of the individual components .

Anti-Suckback Valve
A valve is built into the intake of the SOGEVAC pumps . This “anti-suckback valve” is protected by a metal wiremesh filter . During standstill of the pump (for example due to shutting down or a power failure) the valve closes the intake . This prevents the pressure from rising in the connected chamber while the pump is vented at the same time . Any suck-back of pump oil into the vacuum system is thus also effectively prevented . This blocking process operates under all operating conditions (below 800 mbar (600 Torr)) and even when the gas ballast valve is open .

Compact Design
The pumps have been so designed that efficiency of the pumps will be high .
For the SV 10 B through SV 65 B, the motor and pumping section use the same shaft . For the SV 100 B to SV 1200 the motor is linked depending on requirements to the pumping section directly via a coupling or via V-belts as a pedestal motor . All vacuum components like anti-suckback, exhaust filter with oil return line needed for a complete vacuum unit as well as the optimized placement of all controls and monitoring components allow for an extremely compact unit .
