A vertical centrifugal pump having a support bearing arranged above the pump and including an axial bearing ( 22 ) and a radial bearing ( 23 ). A housing ( 24 ) encasing the support bearing ( 22, 23 ) is directly connected to the flow-carrying housing ( 25 ) of the centrifugal pump. Lubrication, and optionally cooling, of the support bearing ( 22, 23 ) are performed by the pumped medium, which is conveyed to the support bearing ( 22, 23 ) through a connection leading from the pressure zone ( 28 ) of the flow-carrying housing and is discharged into the suction zone ( 29 ) of the pump, and a pump shaft seal ( 31 ) is disposed on the opposite side of the support bearing ( 22, 23 ) from the flow-carrying housing of the centrifugal pump.
