learn moreHow liquid ring vacuum pump works
Liquid ring vacuum pumps typically use a liquid seal to achieve a vacuum. The most widely used liquid is water – typically used once through and rejected to drain. Quite often, a cooling water system is also in place so as to dissipate the heat produced during operation. At this case, a portion of the liquid in the casing is continuously discharged with the gas, collected in a separator
learn moreTwo Stage Liquid Ring Vacuum Pump
To produce vacuum in a twostage liquid ring vacuum pump, a multiblade impeller on a shaft is positioned eccentrically in a cylindrical housing that is partially filled with sealing liquid As the shaft turns, a liquid ring is created by the centrifugal force generated by the rotating impeller.

Liquid ring vacuum pumps and compressors are rotary machines. They operate according to the positive displacement principle. In these machines, a liquid is made to act as a piston. The liquid is generally water for most of the applications and hence they are also known as water ring water piston or liquid piston rotary pumps and compressors.

A liquid ring vacuum pump has an impeller with blades attached to a center hub. The blades are located in the cylindrical body, but are offset from the center. In Figure 1 to the right, you can see the blades near the top of the pump are closer to the outside wall than at the sides and bottom of the pump. You can see this more clearly in Figure 2. The impeller sits between two end plates

Edwards'' liquid ring vacuum pumps play a vital role in maximising efficiency by removing excess air from the system. On exiting the turbine, steam is condensed either by a water or an aircooled condenser, creating a vacuum inside the turbine and therefore increasing efficiency. To maintain this vacuum, air and other noncondensable gases (that leak into and build up within the condenser
