Warning
Take care at the mounting of the micro annular gear pump that in the fault
case leaking liquid cannot get into the motor or the control unit.
!
Take caution measures in the case of a leak so, that damage to adjacent
facilities and the ambient environment are avoided.
Never install a pump in a small installation location without sufficient
ventilation as the motor will be poorly cooled and can overheat.
!
The actuators must be protected against
moisture, dust and perspiration

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.
2.
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.
3.
Connect the fittings with the tubing respectively the pipe work according to
the attached installation instruction.
4.
In the next step seal the pipe fittings at the suction side and discharge side
of the pump head with PTFE tape. This is only valid for 1/8“ NPT inside
thread.
5.
The thread of the fitting should be wrapped with 2-3 layers of PTFE tape
and screwed in the NPT thread (see table 15). First manually, then tightened
with ½ to ¾ wrench turns.
