As water has very low viscosity, the APP pumps
have been designed with very narrow clearance
in order to control internal leakage rates and
improve component performance. Therefore it is
important that the inlet water is ltered properly
to minimize the wear of the pump.
The main lter must have a ltration eciency of
99.98% at 10 μm. We recommend to use
precision depth lter cartridges rated 10μm abs.
ß10>5000 (equivalent to a ltration eciency of
99.98%). Bag lters and string wound lter
cartridges typically have only 50% ltration
eciency. This means that for each 100,000 parti-
cles reaching the lter, 50,000 particles pass
through it compared to only 20 particles in a
lter with an eciency of 99.98%.
For more information on the importance of
proper ltration, please consult our publication
“Filtration” (code number 521B1009), which also
will provide you with an explanation of ltration
denitions and a guidance on how to select the
right lter.
