Preparing for operation

After the liquid supply system had been completed, please check once again
the operating conditions of the micro annular gear pump as according to the
following points:
 Are the inlet and outlet tubes or hoses correctly connected?
 Is the entire liquid supply system clean - that means free of particles, foreign
 Has a filter been installed on the suction side?
 Has a sufficient amount of the right liquid been supplied?

Flushing procedure after use

After each service the micro annular gear pump should be carefully flushed
with a non-corrosive, filtered and particle-free flushing liquid (see table 33 /
table 34). During the flushing procedure the pump should operate at about
3000 rpm and if possible against a low pressure (that can be obtained by using
a restrictor, a capillary or similar). The flushing liquid must be compatible with
the delivered liquid and be suitable for solving the remaining liquid rests.
Depending on the application for example water, or isopropanol may be used.
If you have doubts whether a liquid is suitable for this function or not, please
ask the manufacturer of the liquid or HNP Mikrosysteme.
