2.1
Operating Principle
The machine works on the liquid ring principle.
An eccentrically mounted impeller rotates in a housing partially filled with operating liquid (usually
water). 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, causing gas to be drawn in, compressed and expelled.
