The XD series rotary vane vacuum pump is a single-stage, multi-vane vacuum pump designed for reliable and efficient 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 pump chamber into three working chambers that cycle through suction and exhaust processes. This design allows the pump to remove gas from a container until it reaches its maximum vacuum level.
**Key Features:**
1. **Direct drive system** – compact and lightweight, making it ideal for various applications.
2. **Air-cooled design** – no need for water cooling, simplifying operation and reducing maintenance costs.
3. **Multi-vane construction with rubber pads** – ensures smooth operation and minimal vibration.
4. **Integrated oil separator** – effectively removes oil mist from the exhaust, maintaining cleaner air output.
5. **Automatic oil circulation system** – reduces the need for frequent oil refills.
6. **Built-in automatic suction valve** – isolates the pump from the system when stopped, preventing oil backflow.
7. **High pumping efficiency** – maintains high speed even at near-limit vacuum pressure.
