Abstract

The invention concerns a device for providing automatic circulation in waste water pump stations. On the pressure side the pump unit is provided with a valve (6) which during certain periods opens a connection between the pump and the pump station, thus obtaining a circulation in the latter. The valve (6) is opened and closed by a valve flap (18) which is controlled by the pump pressure. <IMAGE>
