Oil-Sealed Rotary Vane Vacuum Pump

An oil-ring vacuum pump operates by rotating an eccentric rotor within the pump chamber, which forms a moving oil ring to seal and draw in gases. Its function is to create a rough vacuum environment, suitable for applications requiring stable pumping speeds, such as laboratory vacuum distillation and sample degassing.
Selection
When selecting, consider the required vacuum range and match it with the system's airtightness; confirm the pumping speed specification based on the exhaust volume; pay attention to oil compatibility and anti-backflow design; for long-term operation, focus on oil temperature control and maintenance convenience; special materials are required for corrosive gases.
