Definitions

  • the invention relates to a wastewater lifting plant with the features specified in the preamble of claim 1.
  • Sewage lifting plants are used to raise or pump sewage below the level of a sewer or sewer to the level of a higher level sewer. This is the case, for example, in cellars when drains of sanitary objects are located below the sewer system.
  • sewage lifting plants which have a collecting container, in which flows in to be lifted or to be pumped wastewater.
  • a pump unit In or on the sump a pump unit is arranged, which then pumps the wastewater from the sump in a higher-lying sewer line.
  • the switching on and off of the pump unit is carried out depending on the water level in the sump, d. H. upon reaching a predetermined maximum water level, the pump unit is turned on and off when a predetermined minimum water level.
  • DE 24 04 685 discloses a sewage lifting plant for a toilet, which has a container in which a pump unit is used.
  • the pump unit is attached to a plate, which in turn is firmly connected by means of screws with the container top. To remove the pump unit here are thus several screws to solve.
  • FR 2 833 979 A1 discloses a wastewater lifting plant for a toilet with a container and a pump set inserted into the container.
  • This pump unit is held on a plate which is bolted to the top of the container via a plurality of screws. Also in this embodiment, it is thus necessary to remove the pump unit to solve several screws.
  • US 2010/0122744 A1 discloses a sewage lifting plant with a shaft in which one or more submersible pumps are arranged.
  • the pumps are firmly integrated in the shaft via pipes.
  • the shaft also has on its upper side a cover plate with a pivotable lid, which ensures accessibility in the interior of the shaft. The removal of the pumps from the shaft is quite expensive because of the solid casing.
  • a corresponding embodiment of a wastewater lifting plant is off EP 1 035 262 A2 known.
