Liquid ring vacuum pump / two-stage / lubricated / industrial

The liquid ring vacuum pump BLN works by means of an auxiliary
service liquid (usually water) fed into the pump at controlled rate. As
the impeller spins eccentrically to the housing, the liquid is thrown
by centrifugal force to the periphery of the housing. This leaves the
blades of the impeller immersed to their root at one point of the
periphery and only to their tips at the oposite point. As the blades of
the impeller that are totally immersed turn towards the point at which
only their tips are immersed, a void is created in the cavities between
them. At this point, these cavities coincide with the inlet port of the
end-plates and the process air (or gas) is induced into the pump. By
the same but reverse sequence the air is forced out of the ported
end-plate at the other end of the pump establishing a regular transfer.
The degree of vacuum established depends on the energy imparted
to the liquid by the impeller speed and the characteristics of the
liquid.
