Rotary Vane Oil-Sealed Vacuum Pump

A lubricated rotary vane vacuum pump is a type of positive displacement pump that draws in and discharges gas using an eccentrically rotating rotor with vanes that slide in an oil bath. The oil provides sealing, lubrication, and reduces wear, making the pump reliable, efficient, and widely used in industries such as chemical, pharmaceutical, food, packaging, laboratory, and energy.
