4.2 Function
VacuStar WR
The liquid ring pump works according to the positive displacement
principle. At a sufficiently high speed, a rotating liquid ring is
formed in the casing. In conjunction with the impeller, cells form
that are separated from each other and steadily grow (sucking) or
shrink (compressing) with each revolution.
