NOTICE
If applying the configuration shown in figure 4.
The discharge pressure will rise and lead to an increase in shaft power.
• Make sure the cross-sectional area of the gutter is large enough.
NOTICE
If recirculation of the service liquid is not required.
Drainage of the liquid should comply with the appropriate environmental regulations.
WARNING
If handling gas that is flammable or toxic.
Risk of severe injury!
• The drained liquid should be separated twice and transferred to a safe place when ap-
plying the figure 1 arrangement. Particular care should be taken to avoid any leakage
of dangerous gases from the water drain outlet.
WARNING
If applying the configuration shown in figures 2 and 3.
The gas leakage should be controlled according to the local conditions.

SIDE
DISCHARGE
The machine works on the liquid ring principle.
An eccentrically mounted impeller rotates in a housing partially filled with operating li-
quid (usually water). The impeller blades dip into the fluid, and the centrifugal force ex-
erted by their rotation forms a so-called liquid ring within the housing. The pumped me-
dium 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.
