!
In order to protect the interior of the pump from pollution, the pump heads
are delivered with protective plugs. They should be put on when the pump is
at a standstill.
!
For the best performance the suction tube should be as short as possible and
have a large internal diameter.
Warning
In most cases the pump should be operated with a filter featuring pores that
do not exceed 10 µm. The filter protects the pump from particles and dirt.

Assembly instruction for tubing and accessories
Particles or soiling can block or impair the function of the micro annular gear
pump.
Warning
Please check that all wetted parts of the fluidic system are clean. Clean these
parts in case before mounting the pump.
Please check whether there are swarfs in the screw connections, pollution
remaining in reservoirs or soiling in valves, pipe work or filters.
Assembly of the tubing and piping system
1.
Please cut the tubing rectangular with a hose cutter. If metal pipes are
used an intensive cleaning procedure is necessary. After machining the
pipes have to be cleaned and flushed very carefully. Smallest swarfs within
the fluidic system can cause failure of the micro annular gear pump.
2.
Connect the 3/8" fittings with the tubing respectively the pipe work
according to the attached installation instruction.
!
Please note that the correct assembly of tubes respectively pipes with the
pump head is a necessary condition to secure the right direction of flow. When
you want to operate the pump in reverse direction please contact
HNP Mikrosysteme since this is not possible in any application.
3.
The thread of the fitting should be wrapped with 2-3 layers of PTFE tape
and screwed in the NPT thread (see table 8). First manually, then tightened
with ½ to ¾ wrench turns.
