A variety of applications in process engineering is performed under vacuum. For an optimum and efficient process flow, technically mature and reliable vacuum pumping units are needed.
Since the Liquid Ring Vacuum Pump uses water as the working fluid, it is more suitable for situation with high water content in the condenser. Moreover, the Liquid Ring Vacuum Pump is also a Positive Displacement Pump, and its suction capacity can change synchronously with the condenser back pressure. Due to the increase of the condenser air leakage, the back pressure rises. At the same time, the output force of the water ring vacuum pump increases rapidly, thus the increase of condenser pressure can be well restrained to ensure the best output of the generator set. Therefore, most of the condenser vacuum systems of thermal power plants use Liquid Ring Vacuum Pump.
