Strainer
The pump has to be protected from foreign maers
such as weld slag, pipe scale, etc., that could enter the
pump via the suction line. If the cleanliness of the sys-
tem cannot be guaranteed, a strainer must be installed
in the inlet pipe near the pump. For practical reasons
a suction strainer with 0.8-2.0 mm mesh openings is
recommended.
The size of the strainer should be selected so that it is
large enough to allow adequate pressure at the pump
inlet. The pressure drop across the strainer should
preferably not exceed 0.1 bar at max. ow rate and nor-
mal operating viscosity. A vacuum gauge between the
strainer and the pump inlet is recommended to indicate
when the strainer needs cleaning.
