5.8 Suction strainer
When pumping polluted liquid or liquid that may contain solid particles, install a suction strainer in the
suction opening.
– When selecting the suction strainer, carefully consider the mesh width so pipe losses are kept to a
minimum. The net opening area of the suction strainer must be at least three times the cross-
sectional area of the suction pipe.
– In the case of polluted liquids, always install a suction strainer with a sufficiently large net opening
area. The filtration particle size of the suction strainer must be equal to or less than the solids
handling specification of the pump.
– Install the suction strainer such that maintenance and cleaning are possible.
– Make sure the liquid being drawn in has the expected viscosity and can easily flow through the
suction strainer. Heat the suction strainer if necessary.
– Consult the technical specifications for the BA series for the maximum allowable particle size (solids
handling capacity).
