Design and Function
3.1.1 Laboratory-Vacuum-Systems
The Laboratory Vacuum Systems are supplied as a ready-mounted unit.
The chemical-resistant diaphragm pump
(4)
is fitted to the base plate of the column
(3)
and
attached on the suction-side to the separator
(7)
to protect the pump from foreign matter and
on the pressure-side to the KD 500/5 emission condenser
(6)
to recover the condensate.
This ensures that hazardous substances are separated out. The safety valve on the emis-
sion condenser protects against an impermissibly high operating pressure on the outgoing
air end.
The complete vacuum controller, with sensor, venting valve and power unit
(5)
, is fitted in the
column
(3)
. (The non-controlled LVS-variant does not have a controller.)
All exposed glass components
(6, 7)
are coated with transparent plastic as protection a-
gainst bursting. The emission condenser is supplied with insulation.
The power switch
(12)
and the plug for the power cable
(11)
as well as the membrane pump
(10)
, the PC
(13)
control lead
(14)
and the water valve (option)
(15)
are located on the right
of the column.
The LVS types are specially preconfigured according to model.
