General Information

Liquid ring vacuum pumps are in class of positive displacement pumps. Using the expansion and reduction principle in the cell of impeller blade, they vacuum the gases with a liquid ring. If the appropriate liquid is selected (generally water) all the gases and vapors are moved.

For a liquid ring vacuum pump the final suction pressure is limited with the liquid ring evaporation pressure. During service liquid temperature is 15 ºC at the pump discharge vacuum pressure reaches 25 mmHg (33 mbar).

Liquid ring vacuum pumps have a wide application area in industry. Because of their working conditions are in liquid, they are useful for applications which include moisture like filtration, drying, refrigeration and distillation

   Properties:
Safe and efficient operation
able  to  pump  every  kind  of  gas  and  vapors,
works quiet and without vibration
Minimum  maintenance  with  high  efficiency,
Inner  lubrication  is  not  necessary,
The gases which  are  pump  may be saturated  steam,
W ith suitable liquid there is no cleaning problem,
There is not any disorders because there is only one moving part.
There is no leakage with mechanical seal design pumps
Can be used for different applications with proper selection of construction materials and      
  service liquid
