Liquid pump, in particular, detergent liquid pump for household appliances, and method for assembling it

Abstract

A liquid pump includes a rotor, a rotor shaft, and a split cage for accommodating the rotor. A stator assembly is situated outside the split cage, and a pump casing has a pump-casing bottom and top part, a flange part, and a plug-in holder. The pump casing accomodates a pump impeller on the shaft, and the pump-casing top part has a plug-in holder. A method for assembling the liquid pump includes axially pressing a bearing into a bearing holder. O-rings are mounted on the split cage. The rotor is axially inserted into the split cage, which is axially pressed into the plug-in holder of the pump casing. The rotor shaft is simultaneously pressed into the pump impeller. The bearing holder has another supporting part and is axially pressed into the split cage. A cap together with the stator assembly are axially mounted onto the plug-in holder. The pump-casing bottom part is connected to the pump-casing top part, preferably with a pump-casing seal in between.
