Cleaning the pipe system
Notice
Soiling in the pipe system impairs the service life of the pump station. If the pipe system is flushed us-
ing the pump station during the initial commissioning, an additional commissioning filter has to be in-
stalled temporarily before the pump station. Alternatively the strainers supplied as standard can be re-
placed during commissioning by fine-meshed commissioning strainers.

ATTENTION
Damage to device through impurity in the pipe system.
► During welding work attach protective covers in front of the connecting flanges.
► Ensure when welding that welding beads and abrasive dust cannot get into the pipe system and
the pump station.
► Ensure that a commissioning filter is installed when the pipe system is flushed and cleaned using
the pump.
ATTENTION
Damage to equipment through additional pressure loss in the commissioning filter/commis-
sioning strainer.
► Calculate the flow resistance and determine the remaining pump intake.
► Monitor the suction-side pressure.
► Check the commissioning filter/commissioning strainer regularly.
Requirement:
ü
If required, commissioning filter/commissioning strainer installed (mesh width 0.02 mm)
1.
