Leybold SOGEVAC SV 40 B Rotary Vane Vacuum Pump

The Leybold SOGEVAC SV 40 B is an oil-lubricated, single-stage rotary vane vacuum pump designed specifically for industrial applications in the rough vacuum range. It evacuates air and dry, inert gases from a system and compresses them inside a cylinder through the eccentric rotation of a multi-vane rotor. The injected oil simultaneously provides sealing, lubrication, and cooling of the compression unit.

The pump features a compact design with a small footprint and uses a direct motor flange without a coupling, resulting in smooth, reliable operation and consistently low noise levels. Integrated functions such as a built-in anti-suckback valve, gas ballast device, and oil recirculation system ensure efficient and low-maintenance performance. Its application range includes general vacuum tasks in production and engineering as well as fore-vacuum duties in larger vacuum systems.
