ABSTRACT:
The pump for a liquid, especially an electric fuel pump, includes a pump portion having feed members drivable to provide a liquid flow; a housing can having a can base and a housing connector pipe extending from the can base and receiving the pump portion; and an electric drive motor having electrical contacts and a drive shaft connected to the feed members to drive the feed members and a motor housing enclosing the electric drive motor through which the drive shaft extends. The feed members are coupled nonrotatably with the drive shaft projecting through the can base. To provide a simpler assembly and reduced manufacturing costs, the drive motor and the enclosing motor housing are installed as a completely preassembled structural unit in the housing can.
