The vacuum pump (3) generates a vacuum in
the receiving tank (8) and in the suction lines
directly connected to it. As a result of the
pressure compensation, the liquid flows into
the container via the suction lines. A float
switch is located in the receiving tank (8) itself.
It switches off the vacuum pump (3) when the
filling level reaches its maximum. A suction
filter (6) and an air filter (1) are connected
upstream of the vacuum pump (3). These
prevent liquid or dirt particles from entering
the vacuum pump (3). A vacuum regulating
valve (4) is used to set the vacuum. A vacuum
gauge (2) above the vacuum pump indicates
the pressure in the vessel. A sleeve valve (5) is
located at the bottom of the receiver tank (6),
through which the contents can be drained.
