To you all that help me with finding reasons for clogging: pump is
Camelot 642-1, carbide housing and auger with following data
- thread depth is 85microns
- thread pitch is 1,500 microns
- thread peripherical is polished to Ra 40nm /TIR 300 nm
- thread shallow part is polished to Ra 1.5um/TIR 7um
- pressure at syringe level is 2 psi.

Needle removed: still clogging in the pump! Ain't she sweet! Don't know
if Tim wanted to be on his own. Some people do not want to cry out
details worldwide.
