Introduction of Vacuum Pump 

The series of vacuum Pump takes circulating water as working fluid, uses the negative pressure created by fluid jet to eject.
Providing vacuum condition for the processes of evaporation, distillation, crystallization, drying, sublimation, filtration and decompression, degassing and so on, particularly be suitable for labs and small scale test of industries such as universities and colleges, scientific research institutes, chemical industry, pharmacy, biochemistry, foodstuff pesticide, agricultural engineering, biological engineering.

Name: Water Ring Vacuum Pump Manufacturer

Stable performance:

The vacuum degree in general no changes for using continuous, when working time is too long, resulting in water temperature rise and the vacuum degree drops, the user can put the ice for cooling or connecting the water pipes for water circulating.
