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.
