ABSTRACT:
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 the outlet of the valve is directed opposite to the flow direction (A) in the pump housing (4) thus minimizing the risk of clogging.
