• Compact design makes it easier to integrate into devices with limited space
• Liquid level sight glass can quickly indicate the status of pump oil at any time
• Vertical fin heating helps to stabilize the pumping speed, especially suitable for small molecular gases
• Overheat protection switch can provide protection under various overheating conditions
• "Ready" thermal switch sends a signal when the pump is operational
• Three-stage fractionation nozzle plus jet stage can purify pump oil, increase the withstand pressure of the previous stage
• Choose a wide range of pump configurations and flange combinations to optimize pump performance
