13.1 Flanges
The pipes on the intake and discharge side are
connected to intake and discharge connections
via the flanges.
See Fig. 17, Pg. 44.

Mounting
The flanges are mounted when connecting the
pipes/hoses, as described in Chapter 7.3,
"Connecting pipes/hoses (vacuum
pump/compressor)", Pg. 25.
Proceed as follows:
 Screwing flanges onto intake and discharge
connections.
Use commercially available liquid sealant
(e.g. Loctite) when doing so.
Tightening torque: dependent on the
sealant.
 Screw intake and discharge connections
onto flanges.
Use commercially available liquid sealant
(e.g. Loctite) when doing so.
Tightening torque: dependent on the
sealant.
13.2 Non-return valve
The non-return valve is basically a valve with a
plate seat. Its function is to prevent the
pumped gases/vapors as well as the operating
liquid from flowing back out of the pump in
case the operation of the pump-motor unit is
interrupted. It is mounted on the inlet
connection of the unit for this purpose.
See Fig. 18, Pg. 44.

Mounting
The non-return valve is mounted when
connecting the pipes/hoses, as described in
Chapter 7.3, "Connecting pipes/hoses
(vacuum pump/compressor)", Pg. 25.
Proceed as follows:
 Screw on the non-return valve with the
arrow pointing downward on the inlet
connection.
Use commercially available liquid sealant
(e.g. Loctite) when doing so.
Tightening torque: dependent on the
sealant.
 Screw the inlet pipe onto the non-return
valve.
Use commercially available liquid sealant
(e.g. Loctite) when doing so.
Tightening torque: dependent on the
sealant.
