2.1 2.1 Area of application
This lifting station pumps wastewater with and without se-
wagethat occurs below the sewer and backwater level fully
automatically into the sewage system in accordance with the
requirements of DIN 1986. They are only suitable for use for
domestic wastewater, for example in single family and mul-
tifamily homes, hotels and restaurants, department stores,
hospitals, schools or similar commercial applications.
In case the area of application will not allow down time due
to the breakdown of a single pump system, the lifting station
must be equipped with a second pump of the same capaci-
ty which switches on immediately when required (twin stati-
on instead of single station).
