Problems solved by technology

This is difficult because the container is usually not visible from the outside
It is especially problematic to remove the pump unit for maintenance and connect it again without dismantling the entire unit

Embodiment Construction

[0053] The waste water lifting device shown in this exemplary embodiment has a container 2 consisting of two container components 2a and 2b. The container assemblies 2a and 2b are preferably made of synthetic material. The container 2 has an inlet 4 for connection to, for example, a waste water line of a sanitary object such as a toilet. A pump unit 6 is arranged inside the container 2 for pumping the waste water flowing in through the inlet 4 and accumulating in the container 2 out of the container 2 to a higher liquid level. To this end, a liquid level switch (not shown here) for switching on and off the pump is provided in the container 2, which switches on the pump 6 when a predetermined water level is reached in the container 2, and when it is lowered to Second, turn off the pump 6 again when the predetermined water level is lower. On the output side, the pump is connected to a discharge line 8 arranged inside the container 2 , which leads to a discharge connection 10 ....

Abstract

The system has a pump unit (6) arranged in a container. The pump unit has an outlet connector connected with an outlet pipe (8). The pump unit is removably inserted through an opening in a wall of the container. The outlet connector is connected with the outlet pipe by detachable couplings along an insertion direction (X) of the pump unit. The couplings have a coupling part at the outlet connector and another coupling part (16) at the outlet pipe. The coupling parts are in contact with each other in a sealing plane extending parallel to the insertion direction.

Description

technical field [0001] The invention relates to a waste water lifting device having a container and at least one pump unit arranged in the container, the pump unit having a discharge sleeve connected to a discharge line. Background technique [0002] The waste water lifting device is used to lift or pump waste water accumulated below the liquid level of the sewer pipe to above the liquid level of the sewer pipe. For this purpose, known waste water lifting devices have a container into which the waste water to be extracted flows. A pump unit is arranged on or in the container for pumping water from the container into a waste water line at a higher level. [0003] Such devices are known to have a closed container made of plastic, in which the pump unit is mounted through an opening. These containers also have all the necessary connecting lines, in particular also a discharge connection, which is connected on the outlet side to the pump unit. That is to say, within the conta...
