5 Function description
5.8 Options for standard version
The pump station is equipped with one or two strainers as standard. However, these are not capable of
separating larger amounts of soiling occurring regularly or abrasive fine particles. If such operating con-
ditions occur, the station has to be protected additionally by a correspondingly dimensioned operating
filter. Very fine abrasive particles can, however, not be held back by the operating filter and cause in-
creased wear to the pumps. Alternatively the strainers can be replaced during commissioning by fine-
meshed commissioning strainers. A further possibility is the use of an external commissioning filter.
The strainer inserts are made of metal and can be cleaned and reused,
