Abstract (en)
[origin: EP0610866A1] The invention relates to a centrifugal pump with an outlet issuing from the pump chamber 2 and branching into two outlet channels (ducts) 6, 7. Arranged at the branched point 8 is a reversing valve 9 which alternately opens one outlet channel and closes the other outlet channel. The reversing valve 9 switches over automatically in the event of a pressure drop in the outlet to a value of approximately zero or to a negative value (suction). <IMAGE>
