Rotary Vane Pumps
2X-A Two-stage Rotary Vane Vacuum Pump
2X-A two-stage rotary vane vacuum pump is a belt-drive structure with an enormous speed and high vacuum degree. It’s reliable in vacuum coating machine pump systems as a pre-pump. 2X series rotary vane vacuum pump can obtain a vacuum degree under 10-3Torr.it can also be equipped with other vacuum pumps to be a vacuum system. Rotary vane vacuum pumps work in no less than five ℃ at room temperature and not higher than 90% relative humidity environment.
As one of the rotary vane pump manufacturers, suppliers, and exporters of mechanical products, We offer rotary vane pumps and many other products. Please get in touch with us for details.

Applications:
They’re not only used for refrigerators, air conditioners, light bulbs, fluorescent lamps, bottles of bile to production but also used for metallurgy, the chemical industry, light industry, petroleum, medical, pharmaceutical, printing and, dyeing, electronics, electric vacuum, semiconductor, food, atomic energy, textile, oil filter, printing machinery, packaging machines, and other industries. In addition, the vacuum smelting, vacuum brazing, vacuum impregnation, vacuum coating, vacuum heat treatment, vacuum drying, and vacuum packaging process also uses a 2X series rotary vane vacuum pump.
It can be used as the pre-pump of the diffusion pump, roots pump, and molecular pump for electronic instruments, medical equipment, and other supporting application and experimental research.
Because the rotary vane vacuum pump is made of black metal and is more sophisticated, it is unsuitable for suctioning the gas with too much oxygen and toxic, explosive gases; it cannot be used as a compressor and pump. However, If the pump with gas ballast, it can pump condensable vapor gas.
