Water ring vacuum pump

The water ring vacuum pump is equipped with an eccentric rotor with fixed blades. The water (liquid) is thrown into the stator wall to form a liquid ring concentric with the stator. The liquid ring together with the rotor blade forms a variable volume rotary variable volume vacuum pump.

Water-ring vacuum pump was originally used as self-suction pump, and then gradually used in petroleum, chemical, mining, pharmaceutical and food industries and many other sectors. In many industrial processes, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain and vacuum degassing, water ring pump has been widely used.
