PUMP ASSEMBLY

摘要

A pump assembly having a drive module with a stator, a rotor held on a shaft so as to be rotatable relative to the stator, and a housing that circumferentially encloses a portion of the stator. An impeller is held on the shaft, and a hydraulic unit has an intake port through which liquid can be delivered to the impeller. An adapter is connected to the drive module on one side and to the hydraulic unit on the other side. A can body extends between the rotor and the stator of the drive module and encloses the rotor on an end face facing away from the impeller. A can flange adjoins the can body on a side facing the impeller and projects radially outward from the can body. A tubular section circumferentially encloses the impeller at least in part and delimits a pump chamber containing the impeller.

1. A pump assembly for water-carrying cleaning appliances, the pump assembly comprising:
a drive module with a stator, a rotor held on a shaft of the drive module so as to be rotatable relative to the stator, and a housing that circumferentially encloses at least sections of the stator; an impeller for pumping liquid that is held on the shaft; a hydraulic unit with an intake port through which the liquid is adapted to be delivered to the impeller; and an adapted arranged between the drive module and the hydraulic unit, the adapter being connected on one side to the drive module and on the other side to the hydraulic unit, the adapter comprising:
a can body that extends between the rotor and the stator of the drive module, and encloses the rotor on an end face facing away from the impeller;a can flange adjoining the can body on a side facing the impeller, the can flange projecting radially outward from the can body at least in sections;a tubular section that circumferentially encloses the impeller at least in part and that delimits a pump chamber containing the impeller; anda discharge port formed on the tubular section for discharging the liquid from the pump chamber.
