Connections to the Inlet and Exhaust Flanges
Remove the protective caps from both flanges. Connect the system to
be evacuated to the inlet flange, using a centering ring with OR and a
locking collar.
NOTE
For guaranteed reliable sealing, use an OR gasket in Perbunan or Viton.
The inlet duct is equipped with a sieve filter preventing solid
particles from entering and damaging the pump.
NOTE
When the gases to be pumped out contain dust, it is advisable to insert a dust
filter before the inlet flange.
NOTE
When the gases to be pumped out contain large quantities of vapor, it is
advisable to include a condense separator before the inlet flange.
To make best use of the pump’s capacity, use only short, straight
piping, with a diameter not smaller than that of the inlet flange.
NOTE
If rigid piping is used, it is good practice to use a flexible joint in order to avoid
undue forcing of the connection on the pump.
The exhaust duct must be connected to a pipe that will take away the
pumped out gases.
