Abstract: A wastewater-lifting system and a method for operating a wastewater-lifting system guides wastewater loaded with bulky materials into a bulky material collection tank having at least one separating screen. During intake of wastewater, the bulky materials are retained in the bulky material collection tank and pre-cleaned wastewater passes into a liquid collection tank via a connection line and one or both of a pump and a bypass line connected to the connection line. During the wastewater intake a pivoting flap in the connection line closes flow to the pump except for a flushing cross section, and opens the bypass line. During a pumping operation, the pivoting flap opens the connection line from the pump and closes the bypass line.

Abstract: A wastewater-lifting system includes at least one bulky material-collection tank with at least one separating screen arranged in its interior for retaining bulky materials in wastewater loaded with bulky materials passing through the bulky material-collection tank. The system also includes at least one pump connected to the bulky material collection tank via at least one connection line. The separating screen may be removed from and reinserted into the bulky material collection tank predominantly vertically through a closable opening, guided by an inner guide in the bulky material collection tank.

Abstract: A stirrer stand (10) for a submersible motor stirrer (12) composed of at least one base part (14) and a receiving part (16) for the submersible motor stirrer beyond which a guide member extends, which is used for guiding the submersible motor during assembly, the entire stirrer stand being produced from a single vibration-damping material.

Abstract: A guiding device for submersible motor agitators having a guiding tube and a sliding carriage for carrying a submersible motor agitator. The guiding tube is held in a pivotable lower mount and in an upper mount composed of a bracket and an adjusting lug, and the angular position of the guiding tube can be adjusted via the adjusting lug. The sliding carriage, the adjustment lug and any optional connecting lug are dimensioned in such a way that the sliding carriage carrying the submersible motor agitator can be removed from the guiding tube without disassembling the guiding device.
