Clean the internal and external
screw threads leaving no residues.
Make sure the internal and
external screw threads are not
dented or deformed.
Wrap the PTFE tape around the screw
thread clockwise beginning with the
second pitch of screw thread..
The PTFE tape should be wrapped
tightly around the screw thread
approx. two times (720°).
Cut the PTFE tape off and wind
the end of the tape tightly around
the screw thread.
The PTFE tape should not stick out over
screw thread because pieces can be cut
off and get into the system.

Use of PTFE Tape
4.
The suction line should be installed ascending to the pump for better
degassing. The suction line should be designed as short as possible. The
inner diameter of the suction line should be large to guarantee good
priming of the liquid. At the planning of the pipe system take care of
possibilities for degassing.
5.
Operate the micro annular gear pump always with a filter with a pore size
of 10 µm or smaller. The filter prevents that particles or solids penetrate
into the pump what can cause major damage.
6.
Avoid dry running of the pump. Make sure that the liquid flow is not
interrupted.
