The XD series rotary vane vacuum pump is a single-stage, multi-vane vacuum pump designed for efficient and reliable performance. It features an eccentric rotor with fixed vanes that slide radially within the rotor slots. As the rotor rotates, centrifugal force keeps the vanes in constant contact with the pump casing, dividing the chamber into three working volumes that cycle through suction and exhaust processes. This design ensures continuous gas removal from the system until the desired vacuum level is achieved.
**Key Features:**
1. Direct drive system for compact and lightweight construction.
2. Air-cooled design eliminates the need for water cooling, making it easy to operate and maintain.
3. Equipped with rubber pads on the base and multiple vanes to reduce vibration and noise.
4. Includes an oil separator to effectively remove oil mist from the exhaust.
5. Features an automatic oil circulation system that minimizes the need for frequent oil refills.
6. Has an automatic suction valve that isolates the pump from the system when stopped, preventing oil backflow.
7. High pumping efficiency, even at inlet pressures close to the ultimate vacuum level.
