The invention concerns a device for automatic circulation in waste water pump stations. …??The pump unit (2) is provided with a valve (6) at the pressure side, which is arranged to open a connection between the pump and the pump station thus obtaining a circulation. The valve is arranged at the upper side of the pump housing and directed in the flow direction (A) in the pump housing (4) thus minimizing the risk of clogging.
