Fully submersible sewage lifting unit ready for connection with solids separation system in accordance with DIN EN 12050-1. With the solids separation system version, coarse solids are separated before the pumps and do not come into contact with them, thereby maximizing operational reliability. All-in-one gas-tight and watertight collection reservoir without constructive welded joints, as well as two separately-lockable and externally maintainable solids separation reservoirs. Individual shut-off makes it possible to carry out maintenance work during operation. Pumping is performed by two high-performance submersible sewage pumps in dry well installation that run in alternating operation. The dry well installation of the pumps and their configuration as a redundant double-pump system ensures maximum hygiene, ease of maintenance, and operational reliability. The collection reservoir has rounded edges, the tank bottom is bevelled, the deepest point is located directly below the pump. This prevents deposits and the drying of solids at critical points. Quick connector to the pumps and the inspection opening facilitate maintenance work. Separate blocking of the solids separation reservoir facilitate maintenance while the unit is in operation. Manual backwashing in the collection reservoir reinforces the cleaning effect through additional turbulences and the transparent cover on the distributor box allows easy visual inspection of the unit. Level control is carried out using a level probe.
