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 14 and
table 15). During flushing procedure the pump should operate at a speed of
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 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 particular liquid is suitable for this function or
not, please ask the manufacturer of the liquid or HNP Mikrosysteme.
