An eccentrically mounted impeller rotates in a housing partially filled with operating fluid. The impeller blades dip into the fluid, and the centrifugal force exerted by their rotation forms a so-called liquid ring within the housing.
The pumped medium is transported in the spaces between the blades and the liquid ring. The eccentric rotation of the impeller alters the volume of these spaces. Thereby, the gas is drawn in, compressed and expelled.
In single-stage versions, compression is carried out once. In two-stage versions, the pumped medium is compressed again to allow higher vacuum levels to be achieved.
The operating fluid is usually water, but other liquids may be used if required by the process conditions.
Liquid ring vacuum pumps can be operated as a simple continuous flow system, or as a partial or total recirculation system. Operation as a compressor is also possible.

Safe and Environmentally Friendly Loading and Unloading of Tankers in the Port of Gothenburg
130 direct services to destinations in Europe, Asia, the Middle East, Africa and North America: The Port of Gothenburg is the biggest in Scandinavia and the gateway to the world for a large part of Swedish industry. More than 11,000 ships call at the port every year, including many tankers. The aim during the loading and unloading of tankers is to prevent hydrocarbon vapors from escaping. This is where Busch Vacuum Technology comes into play: in a vapor recovery unit that captures hydrocarbons.Learn more
