Abstract The centrifugal pump unit comprises a canned motor with a canned cap which seals the motor winding with respect to the rotor space. The motor is arranged within a motor housing to which there axially connects a pump housing in which there runs an impeller driven by a motor. In the region between the canned cap and the pump housing there are provided sealing means. Between the motor housing and the pump housing there is arranged an adapter, wherein between the adapter and the pump housing there are provided sealing means as well as between the canned cap and the adapter. With the help of this adapter a motor as is known from heating circulatory pumps, with a circumferentially significantly larger pump housing and thus also larger impeller, may be used.
