Clean the filters regularly.
Figure 11: Medium: thin liquids polluted with highly abrasive matter. The back blades
on the centrifugal impeller prevent heavy abrasive matter from getting into
the suction space behind the impeller. To prevent floating abrasive matter
from penetrating the pump, mount a filter in the suction pipe. The straining
capacity of the filter should correspond with the nature of the pollutant. If
necessary, mount several filters with different sieve sizes behind each
other. Use at least one filter with Rp 3/4" connections and a sieve size of
0,6 mm.
