Operating Principle:
In oil-sealed rotary vane vacuum pumps, an eccentrically mounted rotor rotates in a cylindrical housing. Spring-loaded vanes slide in slots in the rotor and seal against the housing wall. The space between the vanes changes during rotation, creating suction and compression. Oil serves for sealing, lubrication, and cooling.

Use as Backing Pump:
SOGEVAC pumps are frequently used as backing pumps for Roots pumps (boosters) to achieve high vacuum. This combination enables:
- ✓ Ultimate vacuum down to 10⁻³ mbar
- ✓ High pumping speed in high vacuum range
- ✓ Fast evacuation of large volumes
- ✓ Efficient operation across wide pressure range
Maintenance and Service Life:
- Oil Change Intervals: 3,000-6,000 operating hours (depending on application)
- Vane Replacement: approx. 10,000-20,000 operating hours
- General Overhaul: after 20,000-40,000 operating hours
- Service Life: 20+ years with proper maintenance
