• The installation of a filter on the suction side is always recommended, particularly when the liquid to be metered contains suspended particles.
• The characteristics of the filter net depend on the kind of liquid and pump flow rate.
For liquids with viscosity not exceeding 200 cp see table D.
• To prevent sucking of impurities, specially when liquids with solid content are
metered, the suction pipe shall not draw the liquid from the bottom of the tank.
The suction point should be 10 cm from the tank bottom (fig.8).
