Performing maintenance
Suction strainer cleaning interval
The filtration unit is equipped with various suction screens depending on its
design.
The suction strainer (5a) has a much larger absorption capacity at a mesh
width of 300 µm than the suction screen (5b) with a mesh width of 100 µm.
This results in very different cleaning intervals for the different versions.

If the effectiveness of the pump falls or if the pump's noise
levels increase, then check / clean the suction strainer.
